The Kalanchoe thyrsiflora, commonly known as Paddle Leaf, is a distinctive and popular succulent. Its unique appearance makes it a favorite for both indoor and outdoor plant enthusiasts.
Identifying Paddle Leaf
The Kalanchoe thyrsiflora is known by several common names, including Flapjack Plant, Desert Cabbage, and sometimes Red Pancake. Its large, fleshy, paddle-shaped leaves grow in a rosette, resembling a stack of pancakes. The leaves are typically gray-green, developing striking red margins in sufficient sunlight. A distinctive powdery white coating, known as farina or epicuticular wax, covers the leaves. This coating protects the plant from intense sun and reduces water loss.
Paddle Leaf Care Essentials
Light
Paddle Leaf plants thrive in bright, direct sunlight, which encourages vibrant red leaf edges and compact growth. Indoors, place the plant in a south or west-facing window for at least four to six hours of bright light daily. Outdoors, full sun is suitable, but afternoon shade can prevent scorching in extremely hot climates. Insufficient light leads to leggy growth and a loss of the characteristic red coloration.
Water
As a succulent, Kalanchoe thyrsiflora stores water in its thick leaves and is highly drought-tolerant. Overwatering is a common issue that can lead to root rot. Allow the soil to dry out completely between waterings. Once dry, water thoroughly until water drains from the pot bottom, ensuring no standing water remains. Reduce watering frequency during winter months when growth slows.
Soil
Well-draining soil is crucial for the health of Paddle Leaf plants. A succulent or cactus mix is recommended, as it provides the necessary drainage. If creating a custom mix, combine two parts potting soil with one part perlite and one part coarse sand to improve drainage significantly. Good drainage prevents water from accumulating around the roots, which can cause fungal infections and rot.
Temperature and Humidity
Paddle Leaf plants prefer warm temperatures and low humidity, reflecting their native arid environment. They thrive in average room temperatures, between 65 to 80°F (18-26°C). Foliage can be damaged around 30°F (-1°C), as they are sensitive to frost. In regions colder than USDA hardiness zone 10, grow them indoors or as an annual outdoors. High humidity can contribute to fungal issues.
Fertilizer
Paddle Leaf plants do not require frequent fertilization. During their active growing season (spring and summer), apply a balanced liquid houseplant fertilizer diluted to half strength once a month. Stop fertilizing in fall and winter when growth slows. Avoid over-fertilization, as it can harm the plant.
Propagating Paddle Leaf
Propagating Paddle Leaf plants is straightforward through leaf cuttings or offsets. For leaf cuttings, carefully remove a whole leaf from the rosette, ensuring a clean cut. Allow the detached leaf to dry and form a callus for a few days before planting. Once calloused, press the cut end into moist, well-draining succulent soil, with the attached end below the surface.
Offsets, also known as pups, are small plants that grow around the base of the mature plant. Carefully separate these from the parent plant, ensuring they have their own roots and foliage. Plant the separated offsets in small pots filled with succulent soil, watering lightly. Both methods benefit from bright, indirect light until new growth indicates establishment.
Addressing Common Paddle Leaf Issues
Paddle Leaf plants show signs when care needs are unmet. Leggy growth, with stretched stems and widely spaced leaves, indicates insufficient light; move the plant to a brighter location. Soft, mushy, or yellowing leaves point to overwatering and root rot; allow soil to dry completely and ensure drainage. Scorched leaves (dry, brown spots) result from sudden intense sunlight; gradually acclimate the plant or provide afternoon shade. Paddle Leaf plants can occasionally attract pests like mealybugs, aphids, or spider mites. These can often be managed by spraying with water or carefully dabbing with a cotton swab dipped in rubbing alcohol.
Safety and Placement
Kalanchoe thyrsiflora is toxic if ingested by humans or pets. All parts of the plant, especially the flowers, contain compounds that can cause symptoms like drooling, nausea, or vomiting. Therefore, the plant should be placed out of reach of children and animals. Outdoors, Paddle Leaf thrives in rock gardens or containers in warmer climates, particularly in USDA hardiness zones 10-12. Ensure good air circulation and protection from frost is also beneficial for optimal growth.
