Adromischus marianiae var. immaculatus Uitewaal
Adromischus marianae var. immaculatus
Adromischus marianiae var. immaculatus is a small succulent with thick stems and fleshy leaves arranged in a spiral on the stem. It is densely branched and constricted at the base. The leaves are oblanceolate or sometimes elliptic, more or less covered with tiny warts, and grow up to 3.6 inches (9 cm) long. They often have brown or white raised and horny margins.
The flowers are upright, up to 0.5 inches (1.2 cm) long, and have 5 fused pale pink to white petals and appear in inflorescences to 25 cm tall with 1- to 3-flowered cymes in mid-summer.
Adromischus marianiae var. immaculatus is native to South Africa. It grows on lower, dry, gravelly slopes, often in the shade of other vegetation, mainly in southern Namaqualand as far north as Springbok and extending southwards into the Tankwa Karoo and the southern Roggeveld Mountains.
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. 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, growing a large specimen can be challenging. In other cases, leaves for propagation must be carefully detached with a sharp knife.
