Kalanchoe Oak Leaf

Kalanchoe beharensis 'Oak Leaf' is a succulent plant with a shrubby habit, native to Madagascar, prized for its foliage covered in a silvery down. Its large, thick, velvety, and beautifully lobed leaves resemble the shape of oak leaves. Its slow growth and ability to tolerate drought in both air and soil make this variety an easy, low-maintenance houseplant. Its habit and texture stand out in a collection of succulents.

Belonging to the Crassulaceae family, Kalanchoe beharensis is also known as Kalanchoe van-tieghemii. It is commonly called Elephant's Ear Kalanchoe due to the size and shape of its leaves, or Behara Kalanchoe. Native to the Behara region of Madagascar, this species grows naturally in xerophytic environments, in dry and rocky areas. In its natural habitat, it can reach up to 3 metres in height, but indoors, it rarely exceeds 1 metre. Its growth is slow but steady. Its opposite, triangular to ovate leaves measure between 10 and 20 cm long and are covered with a fine protective down, giving them a velvety, soft texture. This down reduces evaporation and helps the plant withstand drought. In the 'Oak Leaf' cultivar, the leaves are distinctly lobed, resembling oak leaves. Their colour ranges from olive green to dark green, while their surface may be smooth and powdery or covered in a thick felt of glandular hairs. With age, the foliage develops a rusty hue on top and a silvery underside. Flowering is rare indoors. It can produce small tubular yellow-orange flowers in clusters, but its main appeal lies in its foliage.

To grow Kalanchoe beharensis 'Oak Leaf' indoors, place it in a very bright spot with several hours of direct sunlight per day to maintain its compact habit and silvery hues. A well-draining substrate, such as a mix of cactus compost and sand, is essential to prevent root rot. Water moderately, allowing the substrate to dry out between waterings, especially during active growth periods. In winter, when growth slows, watering should be even more infrequent. This plant tolerates temperatures between 15 and 30°C but should be kept above 10°C, away from cold drafts. It is robust and rarely affected by diseases but may be susceptible to mealybugs.

Kalanchoe beharensis 'Oak Leaf' thrives best in a terracotta pot to facilitate moisture drainage and prevent root rot. It pairs well with other succulents of varied forms, such as Aloe vera or a trailing plant like Senecio rowleyanus, for a striking effect. Its silvery foliage contrasts beautifully with darker or green foliage.
