Scientific Classification

Family: Crassulaceae
Subfamily: Sedoideae
Tribe: Kalanchoeae
Genus: Adromischus

Description

Adromischus cristatus var. schonlandii is a dwarf, succulent plant generally smaller than Adromischus cristatus distinguished by the apical horny margin narrower than the leaf width, plus glandular hairs on the inflorescence and flowers. It has few rosettes on short stems wrapped in a thick coat of reddish, tangled, wiry, hairlike aerial roots. The leaves are up to 1.4 inches (3.5 cm) long, up to 0.8 inch (2 cm) across reversed-triangular to oblong-elliptic, green to grey-green usually lacking nice leaf markings. The flowers are on up to 8 inches (20 cm) long stem, grey-green, ovate-triangular, tipped with reddish white.

Hardiness

USDA hardiness zone 9b to 10b: from 25 °F (−3.9 °C) to 40 °F (+4.4 °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 in spring/autumn and let them dry out between waterings. Adromischus tolerate cool, frost-free conditions during the winter if kept dry. It is as well to keep water off the foliage during the winter. Mealy bugs and vine weevils can be discouraged with a systemic insecticide. Frost hardy to 19 °F (-7 °C).

Many species 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.

Cultivation and Propagation: Adromischus cristatus is a fairly easy succulent to grow and one of the easier Adromischus speciest.
Growth rate: Adromischus cristatus is a popular, fast growing species.
Soil: It prefer well-drained soil.
Repotting: Repot every other years. All species of this genus are happy in small pots.
Exposure: It grows best in a partially shaded position. It got sunburned if exposed to midday sun.
Hardiness: Require a minimum temperature 5°C (But hardy down to -7°C for short periods), with good drainage and dryness in winter to resist the cold.
Watering: It takes more water than cacti, but let the soil dry between soaking, in the wild, it receives rain mostly in spring and fall. Must have very dry atmosphere. Water less in winter but do not allow it to shrivel.
Pest & disease: It is vulnerable to mealybugs and rarely scale. It is prone to rotting from the tuberous base or from dried inflorescences.
Maintenance: As the plant matures, the centre becomes bare. When it does, restart it from side cuttings and throw away the central part.
Propagation: Usually propagate from single leaves (leaf cuttings) or stem cuttings seed propagation is rarely used. Leaves easily root and produce new plants. 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 downward. If grown in a container, bottom watering by immersing the container is recommended.

Its grey-green inflorescences end in similar grey-green small flowers.

Adromischus cristatus var. schonlandii

Adromischus cristatus var. schonlandii is a dwarf succulent plant generally smaller than the standard Adromischus cristatus distinguished by the apical horny margin narrower than the leaf width, plus glandular hairs on the inflorescence and flowers.

Adromischus cristatus var. zeyheri

Adromischus cristatus var. zeyheri is a dwarf succulent that forms groups of stems. The variety ‘zeyheri’ is a light-green form of Adromischus cristatus which is distinguishable by its lack of aerial roots, and with glandular hairs on the leaves, inflorescences and flowers.

Its leaves are larger in comparison to the type species, light green, not mottled, waxy, flattened, oblong about 4-7 cm long and 2,2-5,5 cm wide, widely triangular, and waved/crimped at the margins. Flowers are very small, sessile, and white-cream on a 25-60 cm tall inflorescence.

Flowers are tubular, whitish with some reddish markings, and appear in late winter and spring on up to 12 inches (30 cm) tall, branched stems.

Adromischus festivus

Adromischus festivus is a dwarf succulent, up to 7 cm tall, leaves 2.5 to 5 cm long. It forms groups of stems that are knobbly, stout very short, prostrate, and with sparse branching. Older plants develop a massive caudex or large swollen area near the ground. Stems lacks root-hairs (unlike Adromischus cristatus).

Its leaves are fat, glabrous, small semi cylindrical, more or less mottled with dark green to red based on the exhibition of the plant to the light. Juvenile leaves can be broad with a long margin.

Adromischus filicaulis

Adromischus filicaulis (Adromischus fragilis) is a highly variable and very slow growing adromischus species, usually with shiny grey-green leaves and rust coloured spots and margins.

Two subspecies are recognized, the nominate form and ssp. marlothii (Adromischus marlothii, Adromischus tricolor), but much variation has been recorded for this species that it might seem unnatural to divide it into two subspecies. The main difference is the presence or absence of stiff stilt roots.

Adromischus hemisphaericus

Adromischus hemisphaericus is a succulent perennial, up to 10 inches (25 cm) tall, with suberect or decumbent branches. The leaves are oblanceolate to obovate, rarely orbicular, usually grey-green with or without darker spots and with flaking wax, up to 1.8 inches (4.5 cm) long and up to 1.2 inches (3 cm) wide.

The flowering period of Adromischus mammillaris is in December. Its roots are fibrous.

Adromischus marianae

Adromischus marianae is a bizarre-looking succulent plant with fleshy grey-green leaves spotted brown, but one of the most variable species in the genus and comprises innumerable morphological and geographical variants, every clone is distinct and individuals may be very different one to each other even within the same population.

Some forms are so different that no identifying feature helps to relate them to each other. Cultivated plants can be reliably distinguished only when seeds or details of wild source are available.

Adromischus marianae ‘Blosianus’

Adromischus marianae f. alveolatus

Adromischus marianae f. alveolatus is one of the innumerable morphological and geographical variant of the very variable Adromischus marianae. It is a naturally occurring form similar to Adromischus marianae f. herrei distinguished by peculiar leaves which are shorter less acute, generally more robust, and with a very rough surface. Tubercles are formed occasionally, and very often these run together to form minute and irregularly reticulate, low, rounded ridges. Some of these plants are quite extraordinary in shape.

Adromischus marianae f. herrei

Adromischus marianae f. herrei is a small slow-growing succulent shrub constricted at the base, variable in size up to up to 10 cm tall with many thin and very short branches. It is now believed to be merely a red-brown population of Adromischus marianae with very rough leaves that looks like dried raisins. This species is variable and every clone is distinct and worth to grow more than one sample.

Stems are short, erect, tapering, and basally tuberose. Leaves are green to reddish-brown or purple (depending on clones, growing conditions and seasons), unspotted, becoming grey and waxy as they age. Flowers are green with pinkish-red tinge and about 12 mm long.

Adromischus marianae ‘Little Spheroid’

Adromischus marianae ‘Little Spheroid’ is one of the innumerable morphological and geographical variants of the very variable Adromischus marianae. It is a naturally occurring form distinguished by superb and very peculiar round leaves.

Stems are short, thick ascending often constricted at the base. Leaves are arranged in a spiral on the main stem, sub-spherical to elliptic, slightly concave above, faintly verrucose or almost smooth, and grey-green to greyish brown with a thick bloom.

Adromischus marianae var. antidorcatum

Adromischus marianae var. hallii

Adromischus marianiae var. hallii is a rare plant from the South African/Namibian border, it has the broadest, thickest leaves within the Adromischus marianae complex. Leaves are shorter, more rounded, chalky, grey-green either red spotted or plain. It is a dwarf to low-growing species, stays small and compact with tuberous roots and thick stems.

Adromischus marianae var. immaculatus

Adromischus marianae var. immaculatus is one of the innumerable morphological and geographical variant of the very variable Adromischus marianae. It distinguishes for the cylindrical leaves, but with great variation in marking and texture. This Adromischus species is highly variable and individuals may be very different one to each other even within the same population. Cultivated plants can be reliably distinguished only when seeds or details of wild source are available.

Stems are short, thick ascending often constricted at the base. Leaves are arranged in a spiral on the main stem, oblanceolate or sometime elliptic (rarely obovate), slightly concave on both sides to terete, more-or-less verrucose (or smooth) and never purple-spotted, with an often brown or white raised and horny margin.

Adromischus marianiae var. kubusanum

The leaves are obovate to orbicular, rarely elliptic, up to 1.4 inches (3.5 cm) long and up to 1 inch (2.5 cm) wide, grey-green to grayish-brown with flaking wax and without dark markings. The flowers are white or tinged pink and appear in mid-summer.

Adromischus nanus

Adromischus roaneanus

Adromischus roaneanus also spelled “roanianus” is an odd-looking succulent plant with stem of young plants almost erect becoming prostrate with time. It is one the most variable species in the genus especially regarding the leaf shape and comprises many morphological and geographical variants, every clone is distinct and individuals may be very different one to each other even within the same population.

Some forms are so different that no identifying feature helps to relate them to each other. Cultivated plants can be reliably distinguished only when seeds or details of wild source are available.

Adromischus schuldtianus

Adromischus schuldtianus is a very pretty, compact, perennials succulent shrub, building a branched tuberous base (caudex), variable in size up to 7 cm tall and 15 cm in diameter. The leaves are dusty white-green mottled with few translucent grey-green to maroon spots or unspotted and easily caducous. Three subspecies are recognized, the nominate form subs. brandbergensis and subs. juttae.

Adromischus schuldtianus ssp. juttae

Adromischus schuldtianus ssp. juttae is a much-branched dwarf shrub, up to 10 cm high building a branched tuberous base (caudex). It usually does develop branches longer than those of ssp. schuldtianus. Leaves green, a little glossy, with numerous waxy dots. It is little known subspecies that is, according to Tolken, known only from a few plants.

Adromischus sphenophyllus

This plant has a little branched stem and fibrous roots. Its leaves are grey-green, from rounded to mucronate (“mucronate” is a botanical term which is mainly used to described leaves with a pointy apex). Often, close to the margin, they have red-purple blurs. The margin forms a straight line from broadest point at the apex towards the thin base. In botany, this shape of a leaf is called “lanceolate”.

The flowering period of Adromischus sphenophyllus is in December and January. The flowers are really small (0,9-11 centimeters long), and they are grey tinged red. They are grouped in the typical spike-like inflorescence of the Adromischus species.

Adromischus subdistichus

This plant has fibrous roots and little branches stems. The leaves are rounded, almost circular, dark green-grey, thick, with the margin turning purple-red on the upper part.

The inflorescence develops on a dark red-purple stem, which is much taller than the plant, and is a thyrse, which is the word used in botany to describe a branching flower cluster. Flowers are really small (1 centimeter more or less). The flowering period, as the one of all the other Adromischus species, is in winter.

Adromischus subviridis

Adromischus subviridis is another beautiful, but larger species with white farinose leaves, always with red spots. Their leaves dry up excessively if not given year-round watering.

Adromischus triflorus

Adromischus triflorus is an exquisite dwarf perennial succulent plant forming a cluster with decumbent stems to 20 cm long. The shape and size of the leaves of this species are very variable and a number of local forms can be recognized. Often the leaves have reddish speckles that tend to become more intense in bright light however, sometimes the leaves are devoid of spots.

Flowers are greenish on the outside and white or pink inside the petals. Flowering occurs in summer.

Adromischus trigynus (Calico Hearts)

Adromischus trigynus (also known as Calico Hearts) is a dwarf, compact succulent plant with grey-green leaves mottled and often with a purplish-maroon marginal tinge. It grows up to 1.8 inches (4.5 cm) tall and up to 5 inches (12.5 cm) in diameter.

Leaves are compactly arranged, obovate to nearly orbicular, convex both above and beneath and up to 1.4 inches (3.5 cm) long. Small, white or tinged pink flowers emerge on up to 14 inches (35 cm) long stalks in late spring. They are not particularly showy.

Adromischus umbraticola

Adromischus umbraticola is a perennial with a tuberous, very branched base, and fibrous roots. Leaves are oblanceolated (this is a botanical term used when the shape of a leaf reminds a spear), restricted towards the base, pale green, sometimes with dark spots. the inflorescence is a thyrse (the botanical term for “cluster”), which develops on a 20-35 centimeters long stem, with tiny green tinged pink flowers, 1-1.3 centimeters long.

Cultivation and Propagation: Adromischus cristatus is a fairly easy succulent to grow and one of the easier Adromischus speciest.
Growth rate: Adromischus cristatus is a popular, fast growing species.
Soil: It prefer well-drained soil.
Repotting: Repot every other years. All species of this genus are happy in small pots.
Exposure: It grows best in a partially shaded position. It got sunburned if exposed to midday sun.
Hardiness: Require a minimum temperature 5°C (But hardy down to -7°C for short periods), with good drainage and dryness in winter to resist the cold.
Watering: It takes more water than cacti, but let the soil dry between soaking, in the wild, it receives rain mostly in spring and fall. Must have very dry atmosphere. Water less in winter but do not allow it to shrivel.
Pest & disease: It is vulnerable to mealybugs and rarely scale. It is prone to rotting from the tuberous base or from dried inflorescences.
Maintenance: As the plant matures, the centre becomes bare. When it does, restart it from side cuttings and throw away the central part.
Propagation: Usually propagate from single leaves (leaf cuttings) or stem cuttings seed propagation is rarely used. Leaves easily root and produce new plants. 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 downward. If grown in a container, bottom watering by immersing the container is recommended.
