Description

Adromischus cristatus is a small, slow-growing succulent with branching, up to 2 inches (5 cm) long stems and triangular, pale green, up to 2 inches (5 cm) long and up to 1 inch (2.5 cm) wide leaves covered in tiny hairs. The margin at the tip is undulating. The flowers are tubular, green tipped with reddish-white and appear on up to 8 inches (20 cm) long stem.

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 from spring to fall and let them dry out between waterings. Adromischus tolerates 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.

Adromischus 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.
