Adromischus filicaulis ssp. marlothii

Morphological Characteristics

Adromischus filicaulis ssp. marlothii is a small, clumping succulent from the Crassulaceae family, native to South Africa, particularly found in rocky outcrops of the Western Cape. It is highly prized among collectors for its compact size, unique markings, and sculptural form.

The plant features flattened, obovate to oblong leaves, often slightly undulated or spoon-shaped. The leaf surface is typically gray-green to silvery, marked with irregular maroon to purplish-brown blotches, which become more pronounced in strong light or under stress. The leaves grow on short, woody stems, giving the plant a compact and shrubby appearance.

It generally stays under 10 cm (4 inches) in height, making it ideal for small containers or dish gardens. It occasionally sends up tall, thin inflorescences bearing small, tubular pink to reddish flowers, typically during late spring to early summer.

Growth Habits

Adromischus filicaulis ssp. marlothii is a slow-growing, dwarf succulent that grows as a dense, low mound. It prefers dry, rocky habitats and is best suited for pots, troughs, or rock gardens. It will slowly branch at the base, forming a tidy, miniature shrub over time.

Maintenance Points

• Lighting: Requires bright light to partial sun. Best coloration develops in strong indirect or morning sunlight.

• Watering: Let soil dry completely between waterings. Water sparingly, especially in winter. Overwatering leads to leaf rot.

• Soil: Use gritty, well-draining soil, such as cactus mix with added pumice or coarse sand.

• Temperature: Prefers temperatures between 18–27°C (64–81°F). Protect from frost (minimum ~5°C / 41°F).

• Fertilization: Feed with a diluted succulent fertilizer once during the active growing season (spring or early summer).

• Potting: Shallow pots with drainage holes are ideal. Repot only when necessary—this plant dislikes root disturbance.

• Humidity: Tolerates low humidity and prefers good air circulation.

Reproduction Method

Leaf Cuttings (Preferred):

• Gently remove a mature, healthy leaf.

• Let the leaf callus for 3–5 days.

• Place on dry, gritty soil and mist lightly until roots and new shoots appear (2–3 weeks).

Seeds:

• Rarely used and difficult to obtain. Sow on the surface of moist soil under bright, indirect light.

Additional Tips

• Pest Control: Watch for mealybugs and root aphids. Keep the soil dry and use neem oil or systemic insecticides if needed.

• Disease Prevention: Avoid high humidity and stagnant air. Ensure fast drainage to prevent root rot.

• Pruning: Rarely needed. Remove any dead or shriveled leaves to keep the plant tidy.

• Display: Excellent for succulent collections, miniature gardens, or as an accent in a windowsill tray.

• Safety Note: Non-toxic and safe for home use.
