Genus guide
Gasteria — 14 species
Part of the Aloes & haworthias family (Asphodelaceae)
Gasteria is a genus of compact, slow-growing succulents native to South Africa, prized for their stiff, tongue-like leaves often marked with white warts or spots — hence common names like Ox Tongue. Unlike most succulents they tolerate low to moderate indirect light, making them well-suited to shelves and office windowsills. Water deeply but infrequently, allowing the soil to dry completely between sessions, and use a fast-draining cactus mix to prevent root rot. Toxicity varies across species — check each Gasteria before buying if you have pets.

Gasteria — frequently asked questions
Are Gasteria plants toxic to cats and dogs?
Most Gasteria are pet-safe. Of the 14 Gasteria species we cover, 13 are non-toxic on the ASPCA list and 1 carry a toxic or mildly-toxic rating. Even so, confirm the individual species before trusting it around pets.
How much light do Gasteria plants need?
Most Gasteria do best in bright indirect light. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
Are Gasteria easy to care for?
Gasteria are moderate to grow: the main requirement is a genuinely bright spot out of harsh midday sun. Get the light right and the rest of their care follows.
How many Gasteria varieties are there?
