Pleiospilos nelii 'Royal Flush' (Split Rock)
Description: Pleiospilos nelii, commonly known as 'Split Rock,' is a fascinating succulent species in the Aizoaceae family. It is named for its distinctive appearance, resembling a split or partially open rock. The plant consists of a pair of thick, fleshy leaves that are fused together at the base, forming a slit or cleft down the middle. This cleft serves as a fissure where a new leaf pair emerges during the growing season. The leaves are typically grey-green to bluish-green in color, often with mottled patterns or reddish margins, mimicking the appearance of stones or pebbles. During the blooming season, Pleiospilos nelii may produce daisy-like flowers that range in color from yellow to orange.
Distribution: Pleiospilos nelii is native to the arid regions of South Africa, particularly found in the Northern Cape province. It thrives in rocky, well-draining soils and is adapted to dry, sunny conditions.
Care Tips:
Light:
Requirement: Bright, indirect light.
Details: Pleiospilos nelii prefers bright light conditions. Place it near a window where it can receive plenty of indirect sunlight. Outdoors, it can tolerate some direct morning sunlight but should be protected from intense afternoon sun to prevent leaf scorching.
Watering:
Requirement: Minimal watering.
Details: Water sparingly, allowing the soil to dry out completely between waterings. During the active growing season (spring and autumn), water lightly as needed. Reduce watering in the summer dormancy period to prevent root rot.
Soil:
Requirement: Well-draining soil.
Details: Plant Pleiospilos nelii in a specialized succulent or cactus potting mix. Ensure the soil is well-draining to prevent waterlogged conditions, which can lead to root rot.
Temperature:
Requirement: Moderate temperatures.
Details: Ideal temperatures range from 65°F to 75°F (18°C to 24°C) during the active growing season. Protect Pleiospilos nelii from temperatures below 50°F (10°C), as it is sensitive to cold and frost.
Humidity:
Requirement: Low humidity.
Details: Pleiospilos nelii thrives in dry, low-humidity conditions. It does not require additional humidity and prefers good air circulation around the plant to prevent fungal issues.
Fertilizing:
Requirement: Minimal fertilization.
Details: Fertilize Pleiospilos nelii sparingly with a balanced fertilizer diluted to half-strength during the growing season (spring and summer). Avoid fertilizing during the winter dormancy period.
Repotting:
Requirement: Infrequent repotting.
Details: Repot Pleiospilos nelii only when necessary, typically every few years or when the plant has outgrown its container. Choose a slightly larger pot with good drainage.
Propagation:
Requirement: Seeds or offsets.
Details: Propagate Pleiospilos nelii from seeds, which can be sown in a well-draining seed-starting mix and kept lightly moist until germination. Alternatively, propagate from offsets (pups) that develop around the base of the parent plant. Carefully remove these offsets and plant them in their own pots with well-draining soil.
By following these care guidelines, you can successfully cultivate Pleiospilos nelii 'Royal Flush' (Split Rock), appreciating its unique appearance and occasional delicate flowers in your succulent collection.
