Adromischus filicaulis (Eckl. & Zeyh.) C.A.Sm.
Adromischus filicaulis subsp. filicaulis, Adromischus fragilis, Adromischus fusiformis, Adromischus kleinioides, Adromischus mammillaris var. rubra, Cotyledon filicaulis, Cotyledon fusiformis
Adromischus filicaulis is a slow-growing succulent, usually with shiny grey-green leaves and rust-colored spots and margins. Stems are erect or decumbent, rarely with stilt adventitious roots, up to 14 inches (35 cm) long and up to 0.5 inches (1.3 cm) in diameter. Leaves are up to 3.2 inches (8 cm) long and up to 0.6 inches (1.5 cm) in diameter. Flowers are yellowish-green, up to 0.5 inches (1.3 cm) long, and appear on up to 14 inches (35 cm) tall spike. The corolla tube is yellowish-green, tinged with pink, and lobes are broadly triangular, white or pale yellow, tinged from pink to deep red.
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
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 filicaulis is native to South Africa (Namaqualand, Sandveld).

Central Phoenix -- Adromischus triflorus does not seem to like the sun. Several plants I have tried have died a slow death apparently too much sun. Two potted parts from the same plant, one getting full sun for about an hour in the afternoon and doing only moderately and the other in full shade doing quite well. I have one plant of this in the ground in a mostly shaded location with moderate water. It gets winter protection only from fallen deciduous leaves, and continues to okay, although it remains low and dense with small leaves.

I have not grown this plant. (many variations dependent upon growing conditions in habitat). It forms clusters that have thick, finger-like silvery green tapered leaves. Some variations have deltoid leaves. Often the leaves have reddish speckles that tend to become more intense in bright light however, sometimes the leaves are devoid of spots. Protect from frost (Minimum temperature To 32°F)
Note: Adromischus seeds are very small and seed propagation is rarely used. It is easily propagated by leaf cuttings. Twist off a leaf and permit it to dry out a couple of days, lay it on the soil and insert the stem end partially into the soil. The original leaf should not be removed until it has dried up. Try to keep the leaf somewhat upright so that the roots are able to grow downwar. read more d. If grown in a container, bottom watering by immersing the container is recommended.

Pale blue-green fat succulent leaved low growing plant- good for pots or very open, neat xeriscape gardens (gets lost in crowded ones). Can take more water than you would think without rotting, but recommend water carefully anyway.
All species require a free draining soil mix, extra grit or other material is usually a aded. They are compact growing however will form a good sized clump over time.
It is recommended to repot specimens each year using a fresh potting mix and a little slow realest type fertiliser.
The watering schedule will depend a little on the climate and if grown outdoors or indoors.
Generally less water in summer is recommended, in late summer increase watering and in winter water around once every two weeks, once the growing medium is dry. Watering can be increased again in spring.
In winter, avoid watering the foliage, especially indoors or in warm to temperate climate. Water the foliage in winter can cause fungal problems.
The easiest method of propagation is by removing offsets, however this depends on the species. Leaf cuttings are also reliable. Propagation from seed is also possible.
Powdery Mildew – Caused by damp conditions and poor air circulation.
Snails and Slugs – Especially on new growth.
