Slow-growing, spiny pachycaul succulent from the Richtersveld near the border between South Africa and Namibia, which has a very dry winter-rainfall climate. After many years about half the size of a human (thus the common name), a few feet tall in old age. Sometimes branches from the sides of the main stem, often solitary, responds to loss of the growth center by branching.

A winter grower, and a difficult or impossible plant for locations with wet summers (real risk of rot) unless given overhead protection. Very demanding about strong light. Does best in full sun, especially in winter, and needs excellent drainage. Ideal for dry Mediterranean-type climates with mild winters. Watering schedule is best determined by the growth status of the plant at any given time (water more often when in leaf). This plant may experience extended dormancy and typically goes leafless during summer.
