Cephalophyllum ‘Red Spike’ is a distinctive, low-maintenance succulent from South Africa, known for its vibrant appearance. This plant is well-suited for enthusiasts seeking a visually striking addition to their collection. Its unique characteristics make it a popular choice for rock gardens, containers, or as a vibrant groundcover in suitable climates.
Distinctive Appearance
Cephalophyllum ‘Red Spike’ grows as a trailing, clump-forming perennial succulent. Its compact growth habit typically reaches a height of 3 to 6 inches and spreads up to 18 inches wide, forming a dense mat of foliage. The leaves are fleshy, cylindrical, and often described as finger-like, presenting a grey-green to blue-green color. A striking feature is the reddish tint that develops on the tips or margins of these leaves, particularly in cooler weather or under specific light conditions, contributing to its “Red Spike” name. In late winter and early spring, the plant produces abundant, bright magenta-red, daisy-like flowers, which open during the day and close at night.
Cephalophyllum Red Spike Care
Light Needs
Cephalophyllum ‘Red Spike’ thrives in conditions providing ample sunlight. Full sun exposure is preferred, as it encourages more compact growth and intensifies the vibrant red coloration of the leaves and flowers. While it can tolerate some partial shade, particularly in extremely hot climates, insufficient light can lead to etiolation (stretched, leggy growth). Ideally, this succulent should receive at least six hours of direct sunlight daily for optimal health and appearance.
Watering Practices
Cephalophyllum ‘Red Spike’ is drought-tolerant and susceptible to overwatering, making proper watering crucial. The “soak and dry” method is recommended, meaning the soil should be allowed to dry out completely between waterings before being thoroughly saturated again. This typically translates to watering once every 2-3 weeks, though frequency should be adjusted based on environmental factors like temperature and humidity. During its dormant period, typically in summer, the plant requires little to no water.
Soil Requirements
Well-draining soil is necessary for Cephalophyllum ‘Red Spike’ to prevent waterlogging and root rot. A specialized cactus or succulent potting mix is ideal, as these formulations are designed to provide the rapid drainage this plant needs. Incorporating additional perlite, pumice, or coarse sand can further enhance drainage and aeration, which are beneficial for the root system. The soil pH should ideally range from slightly acidic to slightly alkaline, between 6.1 and 7.8.
Temperature and Humidity
Cephalophyllum ‘Red Spike’ is adapted to warm, arid conditions and tolerates heat well. It grows best in USDA Plant Hardiness Zones 9 to 11, indicating its sensitivity to frost. While it can withstand mild frosts down to approximately 18-26°F (-7.8 to -3°C), prolonged freezing temperatures can cause damage. It thrives in dry air conditions, reflecting its natural habitat, and good air circulation helps prevent fungal issues.
Fertilization
Cephalophyllum ‘Red Spike’ generally has low fertilization needs. During its active growing season, typically spring and early summer, a balanced, diluted succulent fertilizer can be applied every two to three months. Dilute fertilizer to about quarter strength to prevent harm. Fertilization should be withheld during the dormant period in winter.
Propagating Cephalophyllum Red Spike
Propagating Cephalophyllum ‘Red Spike’ can be done through stem cuttings or division. For cuttings, select a healthy, non-flowering stem (3-4 inches long) and allow it to callus for several days to a week to prevent rot. Insert the callused cutting into well-draining succulent potting mix. Keep the soil slightly moist in a bright, indirect light location until roots establish (typically a few weeks). Division involves carefully separating larger clumps into smaller sections, ensuring each has roots attached, then replanting.
Common Challenges
Root rot is a common issue for Cephalophyllum ‘Red Spike’, primarily caused by overwatering or poorly draining soil. Symptoms include mushy stems or leaves and a general decline in plant health. The solution involves immediately reducing watering frequency and ensuring proper drainage. Insufficient light can lead to etiolation, characterized by stretched, pale growth and a loss of the distinctive red coloration. Moving the plant to a brighter location will help. While generally robust, Cephalophyllum ‘Red Spike’ can occasionally be affected by common succulent pests such as mealybugs, which appear as small, cottony masses on the plant. These can be treated with insecticidal soap or by dabbing them with rubbing alcohol.
