Pets
Some pets are less likely than children to eat and touch just about everything. This is good, as a pet owner. However, you know your pet best, and it is up to you to keep them safe. There are plenty of poisonous weeds that can grow within the confines of your lawn, which might make your dogs or cats ill or worse if they eat them. Try to have an idea of what toxic plants grow in your area and keep them under control and your pets away from them.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.
Common Toxic Garden Plants
Common Toxic Garden Plants

Daffodil

Daffodil
Daffodils are a strikingly colorful flower. This can sometimes bring them much attention not from just onlooking adults but children as well. Since kids are more drawn to colorful objects, they may have a higher chance of just grabbing the flower and eating it. Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Once you or your family aren’t feeling well after eating, touching or inhaling anything from toxic plants, please call your doctor for help ASAP!
Outdoor Workers
Outdoor Workers and Recreationalists
Those who enjoy the outdoors either as a hobby or as part of their work will rarely see a plant and decide to munch on it (although the scenario is not unheard of). However, they do tend to deal with moving through and brushing aside plants. These people are more at risk of being poisoned by touching toxic plants than by ingesting them.
Outdoor Workers
Foragers
Foragers
Foraging for food and medicinal plants is a desirable skill among people who want to feel at one with the land. This hobby can be very useful and enjoyable, but if done wrong , it can lead to disastrous effects. People who forage are picking and grabbing plants with the full intention of using those plants, most of the time to ingest them.
Foragers
Children
Children
While outdoor workers are more likely to touch poison and foragers are more likely to ingest poison, children can easily do both. These bundles of joy just love to run around and explore the world. They enjoy touching things and occasionally shoving random stuff in their mouth; this is a terrible combination with toxic plants in the mix.
If you let your children run about, it is important to know what are the local toxic plants that they could accidentally get into. Try to educate the children and steer them away from where the toxic plants are located.

8 most common species:
Hydrangea macrophylla
Bigleaf hydrangea
The bigleaf hydrangea is a deciduous shrub native to Japan, and is known for its lush, oval, colorful inflorescence. The two types of Hydrangea macrophylla are mopheads - with large, ball-shaped, sterile flower clusters, and lace capes - with small round fertile flowers in the center, and sterile flowers on the outer side of each inflorescence. Depending on soil pH, blooms can change color from pink to blue.
Hydrangea quercifolia
Oakleaf hydrangea
The oakleaf hydrangea is native to the southeastern United States, generally found from North Carolina down to Florida. Discovered by William Bartram in the 1770s, it is often used as an ornamental plant in gardens as well as parks.
Hydrangea arborescens
Smooth hydrangea
Smooth hydrangea (*Hydrangea arborescens*) is a deciduous shrub, naturally found on streambanks, gorges, and wooden slopes in many parts of Northern America. It is commonly recognized by its showy inflorescences - big white corymbs which bloom during summer. Smooth hydrangea is often cultivated as an ornamental, and it is an excellent choice for a border plant.
Hydrangea paniculata
Panicle hydrangea
The panicle hydrangea is native to Japan and China. It is commonly used as a winter cultivated flower due to its hardiness. This small tree can grow between 91 cm and 5 m with a maximum diameter of 2.5 m. Its leaves contain cyanide and should not be ingested.
Hydrangea serrata
Mountain hydrangea
The mountain hydrangea is a deciduous shrub that blooms in summer and autumn. It is native to Japan and Korea. The scientific name of this species, Hydrangea serrata, means "water vessel" and refers to the shape of its fruit. It is often planted on borders near homes and patios.
Hydrangea scandens
Climbing Hydrangea
Hydrangea scandens is a flowering plant native to Japan. It is a self-clinging climber with small, fragrant, white flowers. Extreme caution is advised when handling this plant because parts of it are toxic.
Hydrangea aspera
Hairy hydrangea
Hairy hydrangea is named for its hairy leaf undersides. The Latin aspera means "rough," and refers to the same thing. Despite this, hairy hydrangea is a beautiful, award-winning plant with showy flowers that attract butterflies and bees. This bushy, slow-growing shrub has a climbing tendency and so grows well along wall-side borders.
Hydrangea chinensis
Chinese hydrangea
Chinese hydrangea is an exotic and rare medium flowering shrub native to Taiwan. With white lace-capped flowers, this plant can withstand frosts and coastal conditions but prefers partial shade. It is very simple to grow and will complement any garden.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.

Daffodil

Daffodil

Adults have also been known to accidentally grab daffodil bulbs instead of onions.

Why are these mistakes so dangerous? Daffodils contain lycorine, which can induce nausea, vomiting, and diarrhea. It also contains oxalates which can cause swelling and pain. The symptoms can be worse in animals, because if your pets eat daffodils they may experience drowsiness, low blood pressure or even liver damage.

Make sure to call poison control when these symptoms set in. The vomiting and diarrhea have been known to go away after 3 hours, but it is better to be safe than sorry. Ingesting liquids to keep hydration up can be important. If the patient is having difficulty breathing, seek medical attention immediately.

Hydrangea

Hydrangea
Hydrangeas are unique, with their soft blue and pink flowers. They are a great addition to any garden, but should not be snacked on—not that you would want to. Hydrangeas can be especially nasty because they contain compounds known as glycosides. These will release hydrogen cyanide into the bloodstream when consumed. This will block your body’s ability to uptake oxygen to the cells in your body.

The way to combat this kind of poisoning is through getting IVs from the vet or doctor. It is important to contact your medical professional immediately since the symptoms can be fatal within minutes or hours.

Rhododendrons

Rhododendrons
Rhododendron, the state flower of Washington, is also toxic. The multitudinous, pink flowers can be quite dangerous. All parts of this plant are toxic, the leaves and seeds more so than the flowers. However, even the nectar of the flower is toxic and in the Mediterranean, where rhododendrons grow in more dense quantities, the honey from bees who gather rhododendron nectar can be poisonous.

Normally kids and pets do not eat enough to experience the full poisoning effect. However, just eating two leaves is enough to be considered dangerous. The grayanotoxin glycosides within the rhododendron can cause vomiting, diarrhea and irregular heartbeats. Things can get very serious when too much rhododendron is consumed and can lead to necessary medical intervention.

Start by calling poison control first if you suspect anyone has been munching on rhododendrons. The experts there will be able to help guide you through the necessary processes to cure your loved one.

Rhubarb

Rhubarb
Yummy rhubarb has a nasty side to it. While the stems are used in many recipes, including for rhubarb strawberry pie, the leaves are toxic. They contain oxalic acid which is known to blister the mouth, cause nausea, vomiting, diarrhea and kidney stones. The leaves are known to be more toxic to pets than humans, but in either case, it is important to contact poison control immediately to figure out necessary steps to cure the patient.
Common Toxic Weeds in the Yard
Common Toxic Weeds in the Yard

Bittersweet Nightshade

Bittersweet Nightshade
Nightshade is an invasive, noxious weed that is extremely poisonous. It has been found along the East and West Coast of the U.S. It makes its home in areas with disturbed soil. This could be near your garden or areas that have recently had bushes/trees put in.

These plants are dark green with purple flowers that develop into bright red berries. The whole plant is toxic and should be avoided by pets and children alike. If ingested it can cause nausea, vomiting, and diarrhea. The colorful berries are especially enticing to young children. If you see any plants that look similar to tomato or pepper plants that you did not plant in your yard, it is best to just pull them immediately.

Call poison control immediately if you think someone has fallen victim to nightshade.

Buttercups

Buttercups
Buttercups are found throughout the United States, especially in wet areas. The shiny, yellow flowers will pop up in the springtime, accompanying their dandelion friends. However, unlike dandelions, buttercups are not edible.

Buttercups will release a compound called protoanemonin. This toxin is known to cause vomiting, diarrhea, bloody stool, hypersalivation, depression, blisters, and more. These symptoms will affect both humans and animals. The sap may also cause irritation when it comes into contact with skin. These yellow flowers are dangerous and children should be observed cautiously when around them.

Foxgloves

Foxgloves
Foxgloves are beautiful plants that build towers out of vivid purple bell-shaped blossoms. They are very pretty to look at, but they contain a compound known as digoxin. This chemical is used in certain medicines to help people with certain heart conditions. However, the medicine is made by specialists, whereas someone eating foxgloves will receive unregulated amounts of the chemical.

This toxin can make you vomit and lower your heartbeat. This often causes dizziness and faintness. It is extremely important to call poison control immediately to know what to do in the case of foxglove poisoning. Some people have confused the young leaves of foxglove with borage, making adult foragers at risk as well as kids and pets.
How to Tend to or Get Rid of Toxic Plants
How to Tend to or Get Rid of Toxic Plants
Now that you know where to start with toxic plant identification, let us discuss how to either tend to the poisonous plants you decide to keep or get rid of them that plague your yard.

How to Tend to Poisonous Plants

Many plants that are toxic when ingested are also skin irritants. The philodendron is a good example of this. When the sap comes into contact with skin, it can cause a rash to form. To help protect yourself when tending to toxic plants, it is important to wear some sort of gloves.
Tend
Latex gloves may be the best solution due to their disposability. Regular gloves could potentially keep the poisonous sap on their surface. If the gloves aren’t cleaned then you could accidentally touch the irritant or pass it to someone else.

In addition you will want to plan where to keep your deadly beauties. If you have a toxic indoor plant try to keep it up high or out of reach of children and pets. This will keep accidents few and far between. Another idea is keeping your plants in areas that are usually inaccessible to children or pets. Areas such as an office, study room, or guest bedroom could be good locations. If applicable, you could also set up a terrarium for your little plant baby, making it more difficult for curious hands or paws to access.
tend2
If you plan to have outdoor plants, location will be key. You will want to put plants in an area that will be inaccessible to children, pets and even wild animals. You will probably want to avoid planting the plants in the front of your house if kids walk by on a regular basis, just to be cautious. Having the plants behind a fence will be best, but use your discretion when choosing a spot.

How to Get Rid of Poisonous Plants

plants
The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. You can find many herbicides meant for yard use by simply searching the term online. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. If you follow the instructions precisely, then everything should run smoothly for you.

If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. You can manually pull the plants out of the ground. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way.

You can also try pouring boiling hot water or spraying white vinegar on the target plants. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products.

You can also try to use wood chips to cover a certain area where you do not want anything to grow. This will not stop all the weeds, but the few that make it through can be easily picked by hand.

Who Is Most at Risk of Plant Poisoning?
Everyone should keep the following in mind to prevent being poisoned:
1
Do not eat any parts, nor contact with the sap of toxic or unknown plants;
2
If you need to kill it, wear long-sleeved shirts, pants and gloves with sharp tools to dig it out completely;
3
Clean the tools with rubbing alcohol or soap and water but do not do that with bare hands;
4
Clean your hands and skin once exposed to plants with soap and water;
5
Consider using barrier creams that contain bentoquatam to prevent poison oak, ivy and sumac rashes;
6
Dump it in special trash cans in sealed garbage packages;
7
Wear properly when you hiking or working in the wilderness. Long pants, long sleeves, gloves, hiking shoes, etc., that protect you from being hurt by any plants;
8
Once you or your family aren’t feeling well after eating, touching or inhaling anything from toxic plants, please call your doctor for help ASAP!
Outdoor Workers
Outdoor Workers and Recreationalists
Those who enjoy the outdoors either as a hobby or as part of their work will rarely see a plant and decide to munch on it (although the scenario is not unheard of). However, they do tend to deal with moving through and brushing aside plants. These people are more at risk of being poisoned by touching toxic plants than by ingesting them.
Outdoor Workers
Foragers
Foragers
Foraging for food and medicinal plants is a desirable skill among people who want to feel at one with the land. This hobby can be very useful and enjoyable, but if done wrong , it can lead to disastrous effects. People who forage are picking and grabbing plants with the full intention of using those plants, most of the time to ingest them.
Foragers
Children
Children
While outdoor workers are more likely to touch poison and foragers are more likely to ingest poison, children can easily do both. These bundles of joy just love to run around and explore the world. They enjoy touching things and occasionally shoving random stuff in their mouth; this is a terrible combination with toxic plants in the mix.
If you let your children run about, it is important to know what are the local toxic plants that they could accidentally get into. Try to educate the children and steer them away from where the toxic plants are located.

Common Toxic Houseplants
Common Toxic Houseplants
When it comes to decorating a house, there is nothing more refreshing than adding some beautiful houseplants. Some common house plants can also be toxic.

Aloe

aloe
Aloe is famous for its sunburn-soothing properties and its gorgeous desert design. However, many people do not realize that the latex the aloe vera plant produces can be mildly toxic to pets and children.

The latex contains a chemical compound known as saponin. Which when ingested, can cause vomiting, diarrhea, and low blood sugar. This, if left unchecked, can lead to dehydration and electrolyte imbalance. The proper response is to contact poison control or a veterinarian to know what to do in your particular circumstance if either your child or pet consumes aloe.

The latex of the plant is similar to the sap of the tree. It is inside the leaf, but sticks mainly toward the edges. If aloe gel is prepared properly it should be safe for use, but be sure to apply it only topically when treating burns.

Philodendron

Philodendron
Philodendron, also known as sweetheart vine, has become a resident at many houses and even businesses. They are glossy green and the leaves elegantly split, displaying interesting designs. Behind this beauty there is a needle-like toxin called calcium oxalate crystals.

These crystals are held within the plant and only affect you, your pets, or your loved ones if the plant tissue is broken. If ingested, the crystals can cause severe swelling, difficulty breathing, stomach pain, burning and pain. If they are accidentally caught on the skin, they can cause skin irritation.

If anyone accidentally ingests philodendron and they find it difficult to breathe or their tongue starts to swell up, it is important to seek medical attention immediately to avoid suffocation. If you have very young children or pets who have a tendency to tear at plants, keep them away from any philodendrons.

Peace Lily

Peace Lily
Peace lilies produce stunningly white flowers that bring to mind peace and serenity. This is one reason they are invited into our homes and given a place to stay. However, similar to philodendrons, the peace lily contains oxalate crystals known as raphides.

The raphides, once ingested, will cause swelling and burning sensations and can also cause skin irritation. Both pets and humans can get these symptoms so it is important to keep these plants from anyone who is likely to tear or chew it. Symptoms can become dire if the raphides cause the tongue and throat to swell to a point where the person or pet is having difficulty breathing. Seek proper medical attention if this is the case.

Snake Plant

Snake Plant
The snake plant is an interesting and popular house plant. Its stark architecture and wavy coloring has made it a fan favorite. This plant too, however, is toxic when ingested or if the sap touches your skin.

Snake plant sap will cause rashes if it comes into contact with your skin. In addition, it will cause diarrhea and vomiting when ingested. Again these symptoms are very serious and would be best avoided by keeping snake plants out of reach or by choosing a different houseplant.

8 most common species:
Hydrangea macrophylla
Bigleaf hydrangea
The bigleaf hydrangea is a deciduous shrub native to Japan, and is known for its lush, oval, colorful inflorescence. The two types of Hydrangea macrophylla are mopheads - with large, ball-shaped, sterile flower clusters, and lace capes - with small round fertile flowers in the center, and sterile flowers on the outer side of each inflorescence. Depending on soil pH, blooms can change color from pink to blue.
Hydrangea quercifolia
Oakleaf hydrangea
The oakleaf hydrangea is native to the southeastern United States, generally found from North Carolina down to Florida. Discovered by William Bartram in the 1770s, it is often used as an ornamental plant in gardens as well as parks.
Hydrangea arborescens
Smooth hydrangea
Smooth hydrangea (*Hydrangea arborescens*) is a deciduous shrub, naturally found on streambanks, gorges, and wooden slopes in many parts of Northern America. It is commonly recognized by its showy inflorescences - big white corymbs which bloom during summer. Smooth hydrangea is often cultivated as an ornamental, and it is an excellent choice for a border plant.
Hydrangea paniculata
Panicle hydrangea
The panicle hydrangea is native to Japan and China. It is commonly used as a winter cultivated flower due to its hardiness. This small tree can grow between 91 cm and 5 m with a maximum diameter of 2.5 m. Its leaves contain cyanide and should not be ingested.

Fig trees are also important food sources for wildlife in the tropics, including monkeys, bats, and insects.
Rubus
Brambles
Brambles are members of the rose family, and there are hundreds of different types to be found throughout the European countryside. They have been culturally significant for centuries; Christian folklore stories hold that when the devil was thrown from heaven, he landed on a bramble bush. Their vigorous growth habit can tangle into native plants and take over.
Acer
Maples
The popular tree family known as maples change the color of their leaves in the fall. Many cultural traditions encourage people to watch the colors change, such as momijigari in Japan. Maples popular options for bonsai art. Alternately, their sap is used to create maple syrup.
Prunus
Prunus
Prunus is a genus of flowering fruit trees that includes almonds, cherries, plums, peaches, nectarines, and apricots. These are often known as "stone fruits" because their pits are large seeds or "stones." When prunus trees are damaged, they exhibit "gummosis," a condition in which the tree's gum (similar to sap) is secreted to the bark to help heal external wounds.
Solanum
Nightshades
Nightshades is a large and diverse genus of plants, with more than 1500 different types worldwide. This genus incorporates both important staple food crops like tomato, potato, and eggplant, but also dangerous poisonous plants from the nightshade family. The name was coined by Pliny the Elder almost two thousand years ago.
Rosa
Roses
Most species of roses are shrubs or climbing plants that have showy flowers and sharp thorns. They are commonly cultivated for cut flowers or as ornamental plants in gardens due to their attractive appearance, pleasant fragrance, and cultural significance in many countries. The rose hips (fruits) can also be used in jams and teas.
Quercus
Oaks
Oaks are among the world's longest-lived trees, sometimes growing for over 1,000 years! The oldest known oak tree is in the southern United States and is over 1,500 years old. Oaks produce an exceedingly popular type of wood which is used to make different products, from furniture and flooring to wine barrels and even cosmetic creams.
