VINCA

VINCA

The Vinca genus includes seven herbaceous species native to Europe and the Tropics. They are small, annual and perennial plants belonging to the Apocinaceae family, also known by the common name of Periwinkle. Their name comes from the Latin “vincire” = to tie, so called because, in nature, their stems intertwine on the ground. Medicinal substances are extracted from some plants of the Vinca genus. The cultivars currently on sale are trailing plants grown as annuals and, therefore, excellent for use as carpet plants and for borders or even for vases. They require part-shade, but can tolerate full sun if the soil is organic and moist, with a good supply of water. The composition of the substratum for potting must include 70% organic compost and 30% inert material, to guarantee good drainage of excess water. Because of their extraordinary vegetative force and their heavy flowering that lasts all summer, these plants must be fed every fortnight with soluble ternary fertilizers to be added to the irrigation water. They are resistant plants and, if properly cultivated, are rarely attacked by disease.
