About
Crassula rupestris, called buttons on a string, is a species of Crassula native to Namibia and to the Cape Provinces of South Africa. It has gained the Royal Horticultural Society's Award of Garden Merit. It is also called bead vine, necklace vine, and rosary vine.
How to grow it
It prefers well-drained soils, with a good amount of sand, and can be planted in full sun all year round, though it prefers shade during the hottest hours of summer. Watering in summer should be frequent, while in winter it should be almost completely suspended.
The plant is included in USDA Hardiness Zones 9b to 12, therefore it should not be exposed to temperatures below 55 °F (13 °C), and never below 25 °F (−4 °C), although it is preferable that the lower limit is between 41 and 50 °F (5 and 10 °C).
