Catharanthus  roseus Rose periwinkle Tapak dara Apocynaceae
 

Catharanthus roseus, Rose periwinkle, Tapak dara

 

Catharanthus roseus, Rose periwinkle, Tapak dara, vinka  In its original form this shrubby perennial is a rather slender plant about 24 in (60 cm) high, with rose pink flowers shading to a darker red eye in the center.
Garden forms are generally lower and more compact with larger flowers in a wider range of colors, blooming almost throughout the year.
Some mixed color series have flowers ranging from purple through pink to white, while others have mainly pale colors (or white) with prominent red eyes.
All parts of the plant contain poisonous alkaloids from which drugs of value in the treatment of leukaemia have been refined.
Cultivation: In warm climates they will tolerate moderately both deep shade and the fiercest sun, and a dry atmosphere. Grow in free-draining soil, which should be kept moist in the growing period. Tip prune to keep bushy, but not so heavily as to inhibit flowering.
Propagate from seed or from cuttings.
