The Kalanchoe beharensis ‘Fang’ is a distinctive succulent from Madagascar. Its name refers to the tooth-like protrusions on the undersides of its leaves.
Understanding Kalanchoe Beharensis Fang
The Kalanchoe beharensis ‘Fang’ has unique morphology. Its triangular to lance-shaped leaves have a velvety texture from fine hairs (trichomes). These fleshy leaves are grayish-green or bronze upper surface with silvery-gray undersides. The most characteristic feature is the fang-like protuberances or tubercles on the undersides.
This succulent grows upright and bushy, developing into a tree-like shrub outdoors. Indoors, it remains compact. Its cupped form and undulating edges add to its visual appeal.
Care for Kalanchoe Beharensis Fang
Light
Kalanchoe beharensis ‘Fang’ thrives in bright, indirect light. Place it near a south or west-facing window, using a sheer curtain to diffuse intense midday sun. Adequate light maintains compact growth and enhances color.
The plant tolerates full sun outdoors, but direct, harsh sunlight can scorch leaves. Insufficient light leads to etiolation (stretching, legginess, faded leaves). Provide 4-6 hours of bright, indirect light daily, rotating the pot for even exposure.
Water
Watering is crucial for Kalanchoe beharensis ‘Fang’ due to overwatering susceptibility. Use a “soak and dry” method: water until it drains, then allow soil to dry completely.
Frequency varies. During warmer growing seasons, more frequent watering (typically every 2-3 weeks) may be necessary, ensuring the soil is dry. In winter, reduce watering significantly or stop.
Soil
Well-draining soil is essential for Kalanchoe beharensis ‘Fang’ to prevent root rot. A commercial succulent or cactus mix is recommended. Amend with 50-70% mineral grit like perlite, pumice, coarse sand, or lava rock.
Porous potting medium allows excess water to flow easily. Select a container with drainage holes. Unglazed terracotta pots aid evaporation.
Temperature and Humidity
Kalanchoe beharensis ‘Fang’ prefers warm conditions, 65-85°F (18-29°C). It is not cold-hardy; damage occurs below 20-25°F (-6.7 to -3.9°C). Bring indoors if grown outdoors in cold winters.
It tolerates average household humidity. Avoid overly humid environments, contributing to fungal issues. Good air circulation is beneficial.
Fertilizer
Kalanchoe beharensis ‘Fang’ has minimal fertilizer needs. If fertilizing, apply diluted, balanced liquid fertilizer (e.g., 5-10-5 NPK) during active growing season (spring and summer).
Fertilize sparingly (1-3 times yearly). Avoid fertilizing during dormant winter months to prevent salt buildup and root scorch. Over-fertilization is worse than under-fertilization.
Propagating Kalanchoe Beharensis Fang
Propagate Kalanchoe beharensis ‘Fang’ through stem or leaf cuttings. Cuttings require callusing before planting to prevent rot; let the cut end dry to form a protective seal.
For stem cuttings, select a healthy stem, make a clean cut, and plant in well-draining succulent or cactus soil after callusing. For leaf cuttings, gently twist a healthy leaf from the mother plant, ensuring the entire base is intact. Once callused, place it on or slightly into well-draining soil. Keep soil barely moist with bright, indirect light until roots and new growth appear.
Common Problems and Solutions
Kalanchoe beharensis ‘Fang’ is robust, but improper care causes issues. Overwatering is the most frequent cause of root rot. Symptoms include mushy stems/leaves, discoloration, and decline. Allow soil to dry completely between waterings; ensure excellent drainage. If root rot is suspected, repot into fresh, dry, well-draining soil after trimming affected roots.
Insufficient light causes etiolation (stretching, legginess, faded leaves). Move to a brighter location with more indirect sunlight for compact growth. Too much direct sun results in leaf scorching or brown spots; adjust to filtered bright light. Pests like mealybugs or spider mites can affect the plant. Inspect regularly; treat infestations with insecticidal soap or rubbing alcohol.
Safety Considerations
Kalanchoe beharensis ‘Fang’ is toxic if ingested. All parts contain harmful bufadienolides (cardiac glycosides). Ingestion can lead to gastrointestinal upset (vomiting, diarrhea, excessive salivation). More severe symptoms (abnormal heart rhythms, weakness) occur with larger ingestions.
Keep this plant out of reach of children and pets. While contact is not harmful, wear gloves when handling. If ingestion is suspected, consult a veterinarian or poison control.
