Vincas, commonly known as Periwinkles are slender stemmed carpeting plants with glossy evergreen rounded leaves that will thrive in all aspects from full sun to the dense shade under large trees.
Masses of the small flowers appear continuously from early Spring until early Summer (sometimes intermittently until Autumn) nestled amongst the fresh green leaves.
All of these varieties will quickly form a dense weed supressing carpet in any reasonable soil, very drought tolerant once established. Greater Periwinkles (Vinca Major varieties) have larger leaves up to 3cm or so in length and arching new stems. The Lesser Periwinkles (Vinca Minor varieties) have significantly smaller leaves and form a lower carpet of foliage.
