Kalanchoe beharensis, commonly known as Felt Bush or Elephant’s Ear Kalanchoe, is a striking succulent species native to the arid regions of Madagascar. Its unique appeal comes from its large, triangular-lanceolate leaves, which are densely covered in soft, velvety hairs, giving the plant its felt-like texture. These hairs often display a rusty-brown color on the upper side and a silvery-gray underneath. The plant typically develops a thick, woody stem over time, making it a sculptural focal point in any collection.
Providing the Right Environment
Optimal growth requires significant light to prevent the plant from stretching out of shape. It thrives in bright, direct sunlight, which is tolerated because the velvety coating on its leaves acts as a natural sun protectant, diffusing harsh rays. If grown indoors, a south-facing window is the best placement to ensure it receives at least six hours of intense light daily.
Maintaining appropriate temperatures is equally important, as this species is not cold-hardy. The ideal temperature range for active growth is between 75°F and 90°F (24°C to 32°C), mimicking its native environment. Temperatures below 55°F (13°C) can cause distress, and the plant must be protected from frost, which can be fatal. If outdoor temperatures are expected to drop below 40°F (4.5°C), the Felt Bush should be moved to a sheltered indoor location.
Hydration and Substrate Needs
The most common mistake when growing this succulent is overwatering, which quickly leads to root rot. To avoid this, use the “soak and dry” method: water thoroughly until it drains from the bottom, then allow the soil to dry out completely before the next application. During the active growing seasons of spring and summer, this may mean watering every few weeks, but frequency must be adjusted based on heat, light, and humidity.
The potting mix must be porous and fast-draining to prevent moisture from lingering around the roots. A commercial cactus or succulent mix is a good starting point, but it should be amended with non-organic grit materials like perlite, pumice, or coarse sand, often at a 50 to 70 percent ratio, to enhance drainage and aeration. A container with a drainage hole is necessary for the health of this plant. Fertilizer application should be minimal, using a balanced, diluted succulent formula, such as a 2-4-4 N-P-K ratio, applied only once a month during the growing period.
Shaping and Growing New Plants
Pruning maintains the plant’s desired architectural shape and encourages bushier growth. When the plant becomes leggy or tall, trimming the stem just above a leaf node promotes the formation of new lateral shoots, resulting in a more compact specimen. Removing any dead or damaged lower leaves also redirects the plant’s energy toward new, healthy foliage production.
Stem cuttings are the most reliable method for growing new Felt Bush plants and are conveniently obtained during routine pruning. A healthy stem section should be cut cleanly, and the cutting must be allowed to rest for several days in a dry, shaded area until the cut end forms a protective callus. This callousing process prevents rot when the cutting is finally planted in fresh, well-draining soil. Leaf cuttings are also possible, though they take much longer to produce a new plantlet.
