Kalanchoe beharensis is a plant species in the succulent genus Kalanchoe, and the family Crassulaceae. Kalanchoe beharensis is native to Madagascar known by local names mongy, rongy and tavitavy. It may be grown as a houseplant in a bright, sunny windows with sufficient aeration to prevent the proliferation of insect pests. They may live outdoors in mostly frost-free landscapes. It is naturally toxic to humans and cats, and may irritate and itch expose skin; the species is (reportedly) not toxic to dogs, provided the plant has not been treated with any chemicals (according to the National Animal Poison Information network).
Characteristics of Kalanchoe beharensis (Velvet Leaf or Elephant’s Ear Kalanchoe)
- Appearance: This plant has large, thick, felt-like leaves which can grow to impressive sizes, sometimes up to 12 inches or more in length. The leaves are covered with a dense, velvety brown to greenish fuzz that gives them a unique texture and appearance, resembling the skin of an elephant’s ear.
- Leaves: The leaves are arranged spirally around the stem. They can be quite variable in shape, from nearly round to more elongated, often with edges that are wavy or crinkled, adding to the plant’s dramatic look.
- Growth Habit: Kalanchoe beharensis grows as a shrub or small tree, potentially reaching up to 12 feet tall in ideal outdoor conditions, though it’s often much smaller when grown indoors as a houseplant.
- Flowers: It produces small, bell-shaped flowers in clusters that can vary from green to yellow or brown, but flowering is not very common in indoor cultivation.
- Varieties: There are different cultivars and forms, including ‘Fang’ which has leaves with distinct, sharp points along the edges.
Cultivation of Kalanchoe beharensis
- Light: Thrives in bright light with some direct sun. The plant will grow best with at least 6 hours of direct sunlight per day, but too much harsh sun might scorch the leaves, so some shade during the hottest part of the day might be beneficial, especially in very hot climates.
- Water: Water moderately during the growing season, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, so err on the side of underwatering rather than over. In winter, reduce watering significantly as the plant goes into a dormant period.
- Soil: Requires well-draining soil. A cactus or succulent mix is ideal, possibly with added perlite or coarse sand for enhanced drainage.
- Temperature: It prefers warm conditions, with ideal temperatures between 60-85°F (15-29°C). It can tolerate cooler temperatures briefly but should be protected from frost.
- Humidity: It does well in average household humidity. The fuzzy leaves help it cope with lower humidity.
- Fertilizer: Feed with a balanced, low-nitrogen fertilizer formulated for cacti and succulents during the growing season. Fertilize every 4-6 weeks, but dilute to half strength.
- Propagation:
- Leaf Cuttings: Lay leaves on top of soil or insert the petiole into the soil. They will root and produce new plants.
- Stem Cuttings: Cuttings from the stem can also be used, allowing the cut end to callus over before planting.
- Pruning: Prune to shape or if the plant is getting too large for its space. Pruning can also encourage a bushier growth habit.
- Pests: Generally resistant to pests, but watch for mealybugs and scale. Treat with insecticidal soap or neem oil if they appear.
- Repotting: Repot every few years or when the plant has outgrown its container. Choose a pot with ample drainage holes, and only go up one pot size at a time.
Additional Tips
- Handling: Be gentle with the foliage to avoid removing the soft hairs which give the plant its unique texture.
- Growth: While it can grow tall, indoor plants might stay much smaller due to light and space constraints.
- Safety: The plant contains cardiac glycosides which can be toxic if ingested, so it should be kept away from pets and children.
