Kalanchoe beharensis 'Oak Leaf' is another form of Kalanchoe beharensis that is native to Madagascar. Whether this is a true form or a hybrid, I don't know for sure. The gray velvety leaves are smaller to other forms that I grow. Though they are similar in shape and texture, the leaves are only 4 inches (10 cm) long and 3 inches (7.6 cm) wide. We acquired this plant 2 years ago from cuttings with no name attached. In those 2 years, the plant has reached a height of 2.5 feet (0.76 m) tall and wide. The plant freely branches, whereas the other forms usually have only a single trunk. It is very easy to grow and it is a nice addition to our collection.
Blooming: In the 2 years we have had the plant it has never produced blooms.
Culture: Kalanchoe beharensis 'Oak Leaf' needs full sun to light shade with a very well drained soil mix. In the greenhouse, we use a soil mix consisting of 1 part peat moss to 1 part loam to 2 parts sand with small gravel added to ensure good drainage. The plants are very drought resistant and once watered they should be allowed to dry thoroughly before watering again. This form seems to grow faster than other forms and responds well to light fertilizer application on a monthly basis. We use water soluble fertilizer diluted to 1/4 the recommended rate. During the winter months, water is restricted to only enough to keep the leaves from shriveling.
Propagation: Kalanchoe beharensis 'Oak Leaf' is easily propagated by leaf and stem cuttings.
