Adromischus alveolatus, Adromischus marianiae f. alveolatus
This succulent is a cultivar of Adromischus marianiae.
Adromischus marianiae 'Alveolatus' is a small, sparingly branched succulent with tuberous roots and short erect stems that bear chubby, horizontal to erect leaves with a roughened surface, sometimes with small tubercles. The stems are rugose, pale tan-green or yellow-green, occasionally whitish. They are up to 0.8 inches (2 cm) long and 0.2 inches (0.5 cm) in diameter. Leaves are whitish-green, unspotted, and reddish or brownish at the tips. They are obovate or lanceolate, longer than broad, shallowly channeled on the upper surface, up to 1.4 inches (3.5 cm) long, 0.8 inches (2 cm) wide, and 0.5 inches (1.2 cm) thick.
Flowers are yellowish at the base, green above, maroon at the apex, and bright green inside. They are erect, tubular, up to 0.6 inches (1.5 cm) long and 0.2 inches (0.5 cm) in diameter, and appear usually spirally arranged on slender, up to 6.8 inches (17 cm) long, sometimes zig-zag stalks in summer.
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.
