Duckweeds (Lemna)
Duckweeds (Lemna) are fast-growing plants that float freely just beneath the water surface. This genus contains some of the smallest flowering plants around the world. They produce new offshoots rapidly, and although their denseness is a nuisance to humans, it's a great food source for fish and waterfowl.

Exploring the Duckweeds Plants

6 most common species:
Lemna minor
Common Duckweed
Common Duckweed (Lemna minor) are the smallest flowering plants on the planet. The plant is an important food source for both fish and waterfowl. Common Duckweed is used to counteract the effects of agricultural runoff because it removes excessive amounts of nitrogen and phosphorus from waterways.
Lemna trisulca
Star duckweed
Star duckweed (Lemna trisulca) is called duckweed because it is an important food source for fish and birds. This aquatic plant grows in freshwater habitats in temperate regions worldwide. It is a good choice for a garden water plant because it is attractive and less invasive than other duckweeds. It also attracts wildlife and encourages diversity of pond-dwelling invertebrates.
Lemna gibba
Swollen duckweed
Lemna gibba, the gibbous duckweed, swollen duckweed, or fat duckweed, is a species of Lemna (duckweed). It has a simple plant body, known as a thallus, which floats on the surface of the water and measures 3 to 5 mm in diameter. A single root hangs down into the water. Found in a wide range of still or slow-flowing water bodies, this common duckweed can also grow on mud or damp rocks.
Lemna perpusilla
Minute duckweed
Minute duckweed is a tiny aquatic plant that typically forms green carpets across still water surfaces. This free-floating species possesses minuscule, flat, oval fronds that cluster in groups, creating a lush, diminutive mat. Minute duckweed thrives in nutrient-rich freshwaters, reproducing rapidly and contributing to the ecosystem by providing food for aquatic life and shelter for microorganisms.
Lemna turionifera
Turion duckweed
Turion duckweed is a small aquatic plant, often found floating in dense colonies on still or slow-flowing freshwaters. Its tiny, flat, and oval fronds, with their simple root hanging beneath, perform photosynthesis efficiently. During unfavorable conditions, turion duckweed produces compact overwintering buds, known as turions, which sink to the bottom, aiding survival and dispersal.
Lemna disperma
Lemna disperma
Lemna disperma is a small, free-floating aquatic plant. Its flat, oval-shaped green fronds cluster on water surfaces, creating a carpet-like appearance. Adapted to stagnant or slow-moving waters, lemna disperma thrives under full sunlight, using simple roots that dangle for nutrient absorption. Rapid reproduction allows lemna disperma to quickly colonize ponds and calm lake margins, often indicating nutrient-rich environments.

Dracaena
Dracaena
Dracaena are popular house plants that are easy to grow. They can tolerate low-light conditions and require little watering. Their leaves range from variegated to dark green. Their characteristic traits include woody stems that grow slowly but offer a striking appearance for small spaces such as apartments or offices.
Ficus
Fig trees
Fig trees have been cultivated in many regions for their fruits, particularly the common fig, F. carica. Most of the species have edible fruits, although the common fig is the only one of commercial value. 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.
