×Gasterhaworthia 'Rosava' is a small, slow-growing succulent that forms a compact rosette of dark-green leaves with white to cream raised dots. The rosette grows up to 8 inches (20 cm) in diameter. The color fades in the center of the rosette, which can develop a pink to red hue. Leaves are fleshy, fat, smooth, and rather glossy.
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Gasterias are often grouped with Haworthia because the plants have similar cultural requirements. Both are attractive, small succulents that can tolerate more shade than many succulents, making them more suitable as houseplants. However, Gasterias are susceptible to fungal infections, which usually appear as black spots on the leaves. These result from too much humidity or water on the leaves, but they should not spread too quickly. Gasterias have a natural defense mechanism against such fungal attacks and attack the invading organism and seal off the wounded spot. In general, any place where Haworthia and Aloe thrive will be hospitable to a Gasteria.
Gasterias are small, shallow-rooted, and relatively slow-growing. Therefore, they are often grown in small clusters in wide, shallow dishes. Over time, clusters will naturally enlarge as the mother plant sends off small plantlets. When the cluster has outgrown its dish, repot into a new wide and shallow dish with fresh potting soil in the spring or early summer. This is also the time to take offsets for propagation.
Gasteria can be propagated at repotting time using offsets from the mother plant or leaf cuttings, depending on the species.
