What is the plant

The Living Stone plant originates in Africa and has one of the unique appearances among succulents. Shaped and colored like small stones, Living Stones are an extremely easy plant to identify and require little intervention to grow and stay healthy.

With over 140 variations of Lithops, the Rubra stands out for its beautiful, deep red or purple color. It is also a hardy plant that grows close to the ground and is able to survive seasonal droughts. This makes Rubra an excellent choice for first-time plant enthusiasts.

Rubra grows naturally in a desert climate and has its dormant period during the summer. When winter comes and brings rainfall to Africa, the Rubra grows two new club-shaped leaves. They also produce a tiny, daisy-like flower during the summer and fall.

Water
While an easy plant to care for, it should be watered with caution. Once the leaves have fully grown in autumn and into the water, it is safe to water your Rubra. They will not require watering during their dormancy period in summer and will only require little watering during fall, winter, and spring. Be sure to let them dry out fully between waterings.
Sunlight
Living Stones love to be in the sun. They’ll do best in a well-lit room that offers them some shade to keep from overheating. It is recommended to place them in west- or south-facing windows.
Fertilizer
For a succulent that is prone to rot, it is not advised to use fertilizer. They can be fed once during the winter, but it is not necessary.
