Origin
Adromischus filicaulis is native to Namibia and South Africa. It occurs from Rosh Pinah in southern Namibia to Willowmore, Beaufort West, and south Great Karoo in the Western Cape, growing on stony slopes or loamy flats under bushes.
Description
Adromischus filicaulis is a sparingly branched succulent with short branches and grey-green leaves, usually with red to purple spots. It slowly grows and can reach up to 6 inches (15 cm) in height. The stems are thick, fleshy, grey-brown, and can grow up to 14 inches (35 cm) long and 0.5 inches (1.3 cm) in diameter. They are erect or decumbent and rarely with stilt adventitious roots. The leaves are linear-elliptic, measuring up to 3.2 inches (8 cm) long and 0.6 inches (1.5 cm) in diameter.
The flowers can reach up to 0.5 inches (1.3 cm) in length and appear on spikes that can grow up to 14 inches (35 cm) tall in mid-summer. The corolla tube is yellowish-green and red-tinged towards the hairless throat. The petals are white or tinged pink and broadly triangular.
Hardiness
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 also important 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, growing a large specimen can be challenging. In other cases, leaves for propagation must be carefully detached with a sharp knife.
