Adromischus marianiae (Marloth) A.Berger
Adromischus marianae, Cotyledon marianae
Adromischus marianiae is a succulent subshrub that slowly grows up to 6 inches (15 cm) tall. It is a very variable species with usually thin and short branches and small clusters of rough, warty, and nearly spherical leaves resembling dried raisins. The leaves are up to 1.6 inches (4 cm) long and vary in color, from green to red-brown or purplish. Flowers are green tinged with pink and up to 0.5 inches (1.2 cm) long.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °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 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. See more at How to Grow and Care for Adromischus.
Adromischus marianiae is native to South Africa (Little Namaqualand).
