Catharanthus roseus, commonly known as Madagascar periwinkle, is a charming small shrub native to Madagascar. This species has glossy, oval leaves and beautiful flowers that bloom throughout the summer in shades of white, pink, and red. Growing typically to 1 m (3 ft) tall and wide, it thrives in sunny conditions. It is widely used as a bedding plant in tropical and subtropical areas and has gained popularity for its medicinal properties, particularly in treating certain types of cancer due to its alkaloid content.

How to care for Madagascar periwinkle
Water
Water Catharanthus roseus deeply but infrequently, allowing the soil to dry out slightly between waterings. Increase watering frequency during hot, dry periods, but always ensure that there is good drainage to prevent root rot.
Light
Requires full sun to partial shade. While it can tolerate partial shade, flowering is prolific in full sun exposure. Avoid deep shade as this will hinder growth and reduce flowering.
Nutrients
Feed Catharanthus roseus regularly during the growing season with a balanced water-soluble fertilizer every two weeks. Dilute to half the recommended strength to avoid overfeeding, which can lead to poor flowering and weak growth.
Temperature
Prefers warm temperatures typically between 15-30°C (59-86°F). It is not frost-hardy and should be protected from cold drafts and frost. In temperate zones, it may need to be grown as an annual or moved indoors during winter.
