Morphological Characteristics

Crassula pubescens subsp. radicans, commonly known as Large Red Carpet Stonecrop, is a low-growing succulent in the Crassulaceae family, native to South Africa. It is admired for its vivid foliage color changes, sprawling habit, and adaptability in both containers and ground cover use.

This succulent features small, ovate leaves that are green under moderate light but turn rich crimson-red when exposed to bright sunlight or cool temperatures. The leaves grow in opposite pairs along thin, branching, trailing stems that root easily at nodes, forming dense mats.

Mature plants typically grow only 5–10 cm (2–4 inches) tall but may spread 30–60 cm (12–24 inches) or more horizontally. In late fall to early spring, it produces small, star-shaped, yellow flowers in tight terminal clusters above the foliage.

Growth Habits

Crassula pubescens ssp. radicans is a fast-spreading, ground-hugging succulent with a mat-forming growth habit. It’s ideal for cascading over pot edges, covering rocky garden areas, or adding vibrant contrast in succulent arrangements. The plant thrives in dry, sunny conditions and is well suited for xeriscaping or hanging planters.

Maintenance Points

• Lighting: Requires bright light to full sun to maintain compact growth and vibrant red coloration. Partial shade may result in greener, less colorful leaves.

• Watering: Water thoroughly but infrequently. Let soil dry out completely between waterings. Less water is needed during winter dormancy.

• Soil: Use sandy, well-draining cactus or succulent soil. Amending with perlite or coarse sand is beneficial.

• Temperature: Best grown between 18–29°C (65–85°F). Can tolerate light frost briefly, but prolonged exposure below 5°C (41°F) should be avoided.

• Fertilization: Feed monthly with a diluted cactus or succulent fertilizer during the active growing season (spring through early fall).

• Potting: Ideal for shallow containers with drainage. Can be used as a spiller in mixed pots. Repot when the plant becomes too crowded or woody at the base.

• Humidity: Prefers dry air and good airflow. Avoid excess humidity to prevent fungal issues.

Reproduction Method

Stem Cuttings:

• Cut 5–8 cm (2–3 inch) segments of healthy stems.

• Allow cut ends to callus for 1–2 days.

• Plant in dry, well-draining soil and water sparingly until roots form.

Division / Layering:

• Lift and divide mature clumps or rootable branches.

• Replant directly into soil and water lightly.

Seeds:

• Rarely propagated by seed. If used, sow thinly over moist, gritty soil and keep warm in indirect light.

Additional Tips

• Pest Control: Watch for aphids, mealybugs, and fungal gnats in wet conditions. Treat infestations early with neem oil or insecticidal soap.

• Disease Prevention: Ensure quick drainage and avoid letting water sit on leaves or in containers. Good ventilation is important.

• Pruning: Trim back overly leggy or woody stems to rejuvenate growth and maintain a dense carpet form.

• Display: Excellent in rock gardens, low-profile containers, or as a bright red accent in succulent combinations.

• Safety Note: Generally considered non-toxic to pets and humans, but best kept out of reach of curious animals.

🌟 Note: It’s normal for succulents to appear slightly shriveled after shipping. They usually recover within a few days in a suitable environment.
