Description
Ceropegia linearis subsp. woodii, also known as Ceropegia woodii, is a trailing succulent with slender stems and grey-patterned heart-shaped leaves. The stems grow up to 13.1 feet (4 m) long. Leaves are up to 0.8 inches (2 cm) long with an equal width. When exposed to sufficient light, they have a deep green color. Under insufficient lighting, the leaves are pale green. With age, it develops a woody caudex at its base. Flowers are up to 0.8 inches (2 cm) long, usually appear in late summer to early fall, and last up to 6 weeks.

Hardiness
USDA hardiness zones 11a to 11b: from 40 °F (+4.4 °C) to 50 °F (+10 °C).
How to Grow and Care
A gritty compost is suitable, and clay pots help with drainage, especially for the species with white thickened roots and for species forming large tubers. Ceropegias appreciate water and a little fertilizer during warm weather, although some watering care is required for the more difficult species. The vine-like species can suffer from prolonged drought.
Typically, many of these species grow and climb naturally among bushes, which provide shade and humidity to the base, while the vegetative growth is in the light. Where tubers occur, they are best planted on the compost's surface, and the vegetative growth is allowed to twine around supports or trail down from a hanging pot. The latter mode of growth has the advantage of not using valuable bench space. Small tubers formed at joints in the thin stems of some species can be used for propagation. If the tuber rots or dries out, don't panic. As long as some of the top growth is still in reasonable condition, it may be possible to save the plant by re-rooting stems in damp gravel.
