Description
Adromischus cristatus var. schonlandii is a dwarf, often much-branched succulent with short, brittle branches covered with aerial roots and terminal rosettes of green to grey-green, inversely triangular leaves. The branches are up to 1.6 inches (4 cm) long. It is smaller than Adromischus cristatus var. cristatus, distinguished by the leaves with horny apical margins, usually narrower than the leaf, and the inflorescence and flowers with glandular hairs. The fleshy leaves are up to 1.4 inches (3.5 cm) long and up to 0.8 inches (2 cm) broad.
In summer, the plant sends up usually unbranched, up to 8 inches (20 cm) long, spike-like inflorescences with tubular, up to 0.5 inches (1.2 cm) long flowers with a gray-green tubes and white to pinkish petals.
Hardiness
USDA hardiness zone 9b to 10b: from 25 °F (−3.9 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Many species are easy to grow in any free-draining gritty compost. Their compact habit allows a collection to be maintained in a small space, and they grow well on any sunny window ledge or the top shelf of the greenhouse. Water mostly in spring/autumn and let them dry out between waterings. Adromischus tolerate cool, frost-free conditions during the winter if kept dry. It is as well to keep water off the foliage during the winter. Mealybugs and vine weevils can be discouraged with a systemic insecticide. Frost hardy to 19 °F (-7 °C).
Many species can be propagated from a single leaf, which should be placed against the side of the pot so that the stem end is just touching the compost. Some species drop their leaves easily, and although each leaf will form a new plant, growing a large specimen can be a challenge. In other cases, leaves for propagation must be carefully detached with a sharp knife.
