IUCN Red List status: Not Evaluated

The Madagascar periwinkle is valued for both its beauty and medicinal properties.

Along with being grown as an ornamental, the plant is also vital in the production of anti-cancer medications.

Originally only found on the eponymous island, the Madagascar periwinkle is now widely cultivated around the world.

Despite many of Madagascar’s native species being under threat from human activity, the periwinkle has continued to thrive, thanks to its affinity for growing in disturbed areas.

All parts of the Madagascar periwinkle are toxic if eaten. The medicinal compounds must be isolated to become effective treatments.

Madagascar periwinkle grows as a herb or small shrub, sprawling along the ground or growing up to 1m tall. The flowers can be pink or white, with five petals and a long tube connecting them to the stem. The leaves are dark green, oval shaped, and grow in opposite pairs along the stem. The fruits are made up of two narrow, cocoon-like pods, which dry out and open to reveal a number of black, grooved seeds.
