Shack shack
Crotalaria retusa
Also known as: Noxious weed
Many US states classify shack shack (Crotalaria retusa) as a noxious weed since it is a fast-spreading, drought-tolerant plant. The plant is toxic to humans and livestock, containing pyrrolizidine alkaloids. However, despite all these negatives shack shack at least produces attractive hood-shaped yellow flowers.

How much sunlight does Shack shack need to grow?
Exact needs vary, but a minimum of 6 to 8 hours per day is a good rule of thumb for Shack shack to grow and produce fruit.

What type of sunlight does Shack shack need?
Shack shack requires full sun, meaning that it should be grown in a location that gets direct sunlight that isn’t blocked by obstacles such as trees, fences, or buildings. In general, the faster the plant grows, the more hours of sunlight it will need. Morning sun is best for photosynthesis.

Should I protect Shack shack from sun exposure?
Shack shack should not need to be protected from the sun in most climates. Those who live in a desert or near the equator may find that the sun is too harsh for the types of plants they want to grow, but this is the exception.

What will happen if Shack shack doesn't get enough sunlight?
All plants need sunlight to convert into energy. Plants that have a short growing season need even more light and energy than those that grow slowly, as they need to complete all their processes to grow and produce fruit within just a few months.
The first symptoms of insufficient sunlight in Shack shack are pale and yellow leaves that are not able to generate enough chlorophyll to keep their healthy green color. The leaves may eventually fall off, and new growth is small and weak. The plant may become leggy and sparse as it stretches toward the available light.
Finally, without enough light the plant will not be able to produce large, high-quality edible leaves or fruit. Shack shack needs to devote a lot of energy into growing leaves and fruits, so if there isn’t enough light available for it to convert, the harvest will suffer.

What will happen if Shack shack gets too much sunlight?
Shack shack can get sunburned from intense sunlight, especially when coupled with high temperatures and not having enough water. Afternoon sun tends to be most likely to burn plants. Scalded leaves develop faded patches of light brown to white on the areas at the top of the plant that are exposed to the most sun. They are especially vulnerable to this right after being transplanted from a shadier location to being in full sun. Transitioning plants gradually or providing them with a barrier while they are adjusting can help prevent sunscald in young plants.
In many cases, Shack shack develops leaves that are large enough to protect fruits from the strongest rays of the sun. However, if intense sunlight is in contact with fruits, they can also be damaged. Avoid over-pruning those protective leaves so that the fruits don’t get burned.

Are there any cautions or tips for sunlight and Shack shack?
Shack shack may become unbalanced if it gets significantly more light on one side than the other. Ideally, you can plant your Shack shack in a location away from obstacles that might block light, and where the distribution of sunlight is even on all sides.
Be careful about planting tall species next to those that grow closer to the ground. It may not be obvious when the crops are first planted, but over time the taller plants may begin to block the amount of sunlight that can reach the shorter plants.
Morning sun helps to dry dew and precipitation, which helps prevent infection from diseases that can develop when water sits on the plant. If you are watering or irrigating your Shack shack, this should be done in the morning.

Chinese mugwort
Chinese mugwort
Chinese mugwort, a member of the daisy family, closely resembles its relative, the Common mugwort (Artemisia vulgaris). However, chinese mugwort has a more intense aroma, which is how the two are distinguished.It can be toxic to highly toxic if consumed, and even handling can cause skin irritation or allergy reactions.
Chinese violet
Chinese violet
Chinese violet (Asystasia gangetica) is an erect or climbing plant that can grow to be 91 cm tall. It has weak, hairy stems. It is an invasive plant with seeds that disperse and spread aggressively. Chinese violet is native to Africa but grows on nearly every continent.
Arrowleaf sida
Arrowleaf sida
Arrowleaf sida (Sida rhombifolia) is a perennial plant with delicate yellow blooms on stiff, almost woody stems. The stems are used to make brooms, giving it the common name "broom jute." It is also used to make cord and twine.
Orchid tree
Orchid tree
Orchid tree (Bauhinia variegata) is a partially deciduous shrub-like tree that can grow from 6 to 8 m tall. Large fragrant flowers resembling orchids blossom from winter to spring. The colors of the flowers range from orchid purple to light pink all in the same blossom. A fast-growing tree that blooms best in full sun makes a spectacular street tree when grown in warm climates.
Chinese silver grass
Chinese silver grass
Chinese silver grass is a perennial grass that can grow 91 to 213 cm. It forms dense clumps from an underground rhizome. The chinese silver grass is grown mainly as an ornamental grass, with silvery leaves and flowers that vary in color based on the cultivar. Be careful where you plant this type of grass; in some zones it can become invasive.
Callery pear
Callery pear
The callery pear is native to China but is considered invasive in the U.S and Australia. Although it does not self-pollinate, it can become invasive by hybridizing with other plants to create fertile fruits that may seed in natural areas. The callery pear creates large populations of fruits that are spread by birds and animals and readily root in disturbed areas. It also forms thick colonies that may compete with other native species for natural resources. Alternative plants include the Trident Maple and the Serviceberry. The callery pear can be controlled by manually pulling young plants, and a range of herbicides such as oil-based herbicides, foliar herbicides, and both basal bark and stump treatments. It is important to remove seed sources as the weed can reinvade areas where it has been previously removed.
