How to Grow and Care

Haworthias are not considered difficult houseplants to grow—if you can keep a pot of Aloe alive on a windowsill, chances are you can do the same with a dish of Haworthia. As with all succulents, the most dangerous situation is too much water—they should never be allowed to sit in water under any circumstances. At the same time, these little decorative plants can be grown in interesting containers such as teacups and even miniature baby shoes. If you're given a Haworthia in such a container, make sure the container had adequate drainage. If it doesn't, it might be a good idea to pop the plant out of its container and add a layer of gravel to the bottom to reduce the soil's wicking action above. Finally, look out for sunburned spots on your plants.

Haworthias are small (usually remaining between 3 inches (7.5 cm) and 5 (12.5 cm) inches in height) and relatively slow-growing. They are often grown in small clusters in wide, shallow dishes. See more at How to Grow and Care for Haworthia.

Probably a hybrid of Haworthia cymbiformis and Haworthia retusa.
