Adromischus zeyheri, Cotyledon zeyheri
Adromischus cristatus var. zeyheri is a small succulent with short branches and spoon-shaped, pale to bright green, unspotted, and hairless leaves. The rounded upper part of the leaf blade tapers in thick succulence to the narrow base. The rounded leaf tip is wavy. The flower spike is lax, comprising tiny flowers with cylindrical green tubes above a small calyx. The five whitish-cream pointed corolla lobes are tinged pink on their outside keeled surfaces. Fruits are dry many-seeded follicles.
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, it can be a challenge to grow a large specimen. In other cases, leaves for propagation must be carefully detached with a sharp knife.
