Periwinkle Flowers are very common in Goa, blooming in every house garden.
Periwinkle flowers are derived from two genera in the apocynaceae family – the vinca, better known as the common periwinkle, and catharanthus, often called the Madagascar periwinkle. They are both relatively small species – the Madagascar variety numbering around eight, while the vinca hosts a meager five species to its name – and are strikingly similar in many ways. For instance, both have petite, five-petaled blossoms; long growing stems which can range between 3 to 30 inches above ground; and both types have glossy, bright green foliage. The Madagascar periwinkle is native to areas of southern Asia, while vinca is indigenous to Europe, Asia and Africa. The hues of these flowers can range from white and violet, to rose, pink and red.
