Wrightia antidysenterica aka Coral Swirl

Wrightia antidysenterica comes from Sri Lanka. This evergreen shrub keeps its leaves all year. It belongs to the Apocynaceae family. Kew lists it as a shrub or tree. Useful Tropical Plants calls it a small, compact shrub. It gives a height of about 5 feet [1.5 metres]. The sources give no height range for its tree forms. They give no mature width or rate of growth.

White flowers are its main draw in gardens. Useful Tropical Plants says it blooms in all seasons. This makes it useful where blooms that last matter. The source records wild plants and plants grown for show. It gives no details of flower shape or scent. It does not describe the fruit or leaf shape. Nor does it describe bark texture or stems.

Kew places it in the wet tropical climate group. This tells us about its home, not how to grow it. The sources give no tested cold limit or hardiness zone. They give no clear needs for light, soil, or water. Useful Tropical Plants says growers can raise it from seed. It gives no sowing method or time for seeds to sprout. The sources name no pests, diseases, or weed problems. These gaps do not mean the plant has none.

People gather wild plants for use in local medicine. Useful Tropical Plants lists uses for bark, leaves, and seeds. It says the bark has antimicrobial and anti-inflammatory effects. These mean it acts against microbes and inflammation. Past uses include dysentery and sores in the mouth. People use bark juice on mouth sores. They apply dried, ground bark for dropsy, a swelling disorder. The source also notes bark use as an adulterant. This means mixing it into another product used as medicine. These records show uses, not proof that treatment is safe.

People have used the leaves for psoriasis and other skin complaints. Recorded seed uses include fever, diarrhoea, and dysentery. People also use them to treat worms in the gut. The source calls the seeds astringent, meaning they tighten tissue. It also says they reduce fever. It lists no known food uses for this species. It reports no known hazards but gives no safety tests. This does not prove people or pets can eat it safely.
