Common Names: Periwinkle, Madagascar Periwinkle, Cape Periwinkle, Rose Periwinkle, Rosy Periwinkle, Old-Maid, Vinca
Species: Catharanthus roseus
Family: APOCYNACEAE
Vincas are nearly always in flower, and can become quite weedy here in Brisbane, Australia if left unchecked. This particular white cultivar of Catharanthus roseus has been self-sowing itself in my garden for at least several generations. Despite this in its natural environment in Madagascar, Madagascar Periwinkle is actually endangered due to extensive agricultural clearing.
