Vinca major is a trailing vine, spreading along the ground and rooting along the stems to form dense masses of groundcover individually 2–5 m across and scrambling up to 50–70 cm high.
The leaves are opposite, nearly orbicular at the base of the stems and lanceolate at the apex, 3–9 cm long and 2–6 cm broad, glossy dark green with a leathery texture and an entire but distinctly ciliate margin, and a hairy petiole 1–2 cm long.
The flowers are hermaphrodite, axillary and solitary, violet-purple, 3–5 cm diameter, with a five-lobed corolla. The calyx surrounding the base of the flower is 10–17 millimetres (0.39–0.67 in) long with hairy margins. The flowering period extends from early spring to autumn.
Shrub about 4.5' tall. Pointed leaves up o 6" long. Flowers magenta.
Roughly 1 meter in height with simple waxy leaves and green pods for seeds. Seed pods have ridges, and are filled with hair-like seeds.
