How to Grow and Care

Madagascar Periwinkle is native to Madagascar but is cultivated and naturalized in most of the tropical world and in warmer climates in the United States. It can be found in a variety of woodland, forest and grassland locales, but one of its primary uses is a bedding plant in highway medians or commercial landscapes. Madagascar Periwinkle also makes a striking clumping plant for home gardens as ground cover, in beddings or edgings or in containers.

Unlike many other plants, Madagascar Periwinkle is best suited for poor, well-drained soil and may even fail to thrive in soils that are too fertile. These plants need regular moisture but don’t do well with overhead watering. Madagascar Periwinkle is easily propagated with semi-ripe cuttings planted in light compost with bottom heat and high humidity, or by seeds kept in the dark at 71 to 77 degrees Fahrenheit (22 to 25 degrees Celsius) until germination. The leaves may curl during the heat of the day but recover with evening dew. The flowers drop off after blooming and don’t require deadheading… – See more at: How to Grow and Care for Madagascar Periwinkle (Catharanthus roseus)
