Catharanthus Roseus Apocynaceae MADAGASCAR PERIWINKLE Plant Care

This plant is related to the blue-flowered periwinkles, Vinca spp., but produces white, pale violet, or pink star-shaped flowers with a deeper- colored throat. The oval leaves are bright green and shiny, and flowers are produced in profusion at the tips of the stems.

Catharanthus roseus aroused much interest some years ago when its wild form was found to produce a drug useful in the treatment of leukemia. It is not demanding and is available at garden centers in spring. It fairly easy to raise from seed and can be a good outdoor annual.

Shiny, healthy-looking oval leaves have a light-colored midrib.

Star-shaped flowers, with slightly reflexing petals, are about lin/2.5cm across and are often carried in large numbers.

Seedlings produce the healthiest, most free- flowering plants.
