Ceropegia linearis E. Mey.
String of Needles
Ceropegia linearis subsp. linearis, Ceropegia caffrorum
This species is native to South Africa.
Ceropegia linearis is a climbing semi-succulent plant that produces a cluster of slender stems from a tuberous rootstock. The stems are annual or perennial and grow up to 6.6 feet (2 m) long. The tuber is up to 1.2 inches (3 cm) in diameter. Leaves are green, glabrous, somewhat fleshy, shortly petiolate, up to 2 inches (5 cm) long and about 0.25 inches (0.6 cm) wide. Flowers are white to pale magenta, up to 1.2 inches (3 cm) long, and usually appear from late summer to early fall and last up to 6 weeks.
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 species that form large tubers. Ceropegias appreciate water and a little fertilizer during warm weather, although some watering care is required for the more delicate 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 allows them 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.
