Description
Conophytum obscurum is a dwarf succulent that grows in dense clusters of inversely conical bodies consisting of thick, almost entirely fused leaves. The clusters can reach a diameter of 6 inches (15 cm). The bodies have a truncated to concave upper surface, are shiny, and vary in color from bright green to deep blackish-green. They can be smooth or have crocodilian-like bumps, sometimes spotted with red.
During the fall, Conophytum obscurum produces long-tubed flowers with an externally magenta tube, pink to white petals, and red or magenta filaments. The flowers open during the daytime.
How to Grow and Care for Conophytum obscurum
Light: This plant thrives in bright light but should be protected from intensive direct sunlight. To avoid sunburn, place it in an area where it can receive a few hours of full sun during the cooler parts of the day.
Soil: For optimum growth, Conophytum obscurum requires porous soil that allows water to drain away quickly. You can use a commercial potting mix designed for succulents or make your own.
Temperature: This plant can tolerate high temperatures but is not frost-hardy. It grows best in USDA Plant Hardiness Zones 10b to 11b, with average minimum winter temperatures ranging from 35°F to 50°F (1.7°C to 10°C).
Watering: Conophytum obscurum requires little to no water during its dormancy from spring to summer. When it begins to grow again in the fall, it is safe to water it deeply. However, ensure that the soil dries out between waterings. If the leaves begin to wrinkle during the active growth, it may indicate that the plant needs additional water.
Fertilizing: This plant is a light feeder and does not need fertilizer if repotted every two years.
Repotting: The best time to repot this plant is at the beginning of the growing season, but it can also be done at any point during active growth.
Propagation: Conophytum obscurum is usually propagated from seeds, but can be easily propagated by division. The ideal time to divide the plant is before it starts to break dormancy or after flowering.
