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 somewhat more shade than many succulents, making them more suitable as houseplants. 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. 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. See more at How to Grow and Care for Gasteria.


x Gasteraloe 'Twilight Zone' is a hybrid cross between Aloe haworthioides and Gasteria carinata, created by Kelly Griffin, who develops hybrids for Altman Plants. He named it for the intro to Rod Sterling's Twilight Zone with the floating stars coming at you like driving in a snow storm.
