The leaves are oval to oblong, 2.5–9 cm (1.0–3.5 in) long and 1–3.5 cm (0.4–1.4 in) wide, glossy green, hairless, with a pale midrib and a short petiole 1–1.8 cm (0.4–0.7 in) long; they are arranged in opposite pairs.
Vinca difformis in habitat, Cáceres, Spain. Vinca plants are subshrubs or herbaceous, and have slender trailing stems 1–2 m (3 + 1 ⁄ 2 – 6 + 1 ⁄ 2 ft) long but not growing more than 20–70 cm (8– 27 + 1 ⁄ 2 in) above ground; the stems frequently take root where they touch the ground, enabling the plant to spread widely.
Catharanthus roseus, known formerly as Vinca rosea, is a main source of vinca alkaloids, now sometimes called catharanthus alkaloids. The plant produces about 130 of these compounds, including vinblastine and vincristine , two drugs used to treat cancer.

Blue dicks-ookow (Dipterostemon capitatus): one of the most common native bulb species throughout California; found in grassland and dry meadow habitats Mariposa lilies ( Calochortus spp.): available from reputable horticultural sources; taking from the wild is illegal and is resulting in significant declines of some species from over collecting.
The plant is a congeneric of the Madagascar periwinkle (C. roseus), the original main source of vinca alkaloids, also known as catharanthus alkaloids, which are still in use today as anticancer drugs. C. trichophyllus contains lower concentrations of such alkaloids. The two species can be hybridized to increase the concentration. [2]
Northern coastal scrub and coastal prairie generally occur where the Pacific Ocean moderates summer drought. As a result, northern coastal scrub not only traces the Pacific Coastline from central California to Southern Oregon, but extends inland, following the distribution of marine climate influence, appearing where the winds press coastal fog inland.
