What is Conophytum?

Conophytum is a genus of flowering succulents native to South Africa and Namibia. These distinctive plants are among several genera known as “stone plants” because of their resemblance to stones. Gardeners in warm climates can cultivate Conophytum species outdoors in their gardens, while gardeners in other regions of the world will need a greenhouse or a warm spot in the home. Several species are widely circulated in gardening communities, along with a number of hybrids.

These plants produce pairs of fused leaves. The level of fusion depends on the species, with some pairs being partially split along one side, while others form rounded, knobbly growth. Depending on the species, a Conophytum can resemble a pile of rocks or buttons, with foliage ranging from green to bluish-green to gray in color. As with other succulents, the leaves are typically thick and fleshy, designed to help the plant store water.

The brightly colored flowers can be pink, brown, yellow, purple, white, and other colors, depending on the species and the cultivar. Conophytum species are usually dwarf succulents and will not grow very large over the course of their lifetime. They are typically cultivated from seed, although nurseries propagate with clones as seeds do not always breed true. Gardeners interested in growing from seed can order seeds or ask fellow gardeners if they have seeds for sale or trade.

These plants can be grown outdoors in USDA zones 10 and 11. They prefer well drained soil and full sun to partial shade. Like other succulents, Conophytum are very well suited to low water gardening. Their showy appearance can make them ideal for showcasing as garden features and they can also be used in borders and beds. Because they do not grow very large, these plants are not suitable for background plantings, as they can be overwhelmed by larger plants in the garden.

When growing indoors, people who do not have greenhouses should seek out places in the house with bright, indirect light and lots of warmth. Succulent soil mixes are available for growing plants like Conophytum. It is important to regularly check the soil, as it can dry out quickly, and while succulents are designed for drought conditions, they do not appreciate being left in bone dry soil for extended periods of time. Fertilizer mixes are available and gardeners should be advised that these plants are primarily wintergrowing, and thus benefit from extra encouragement in the winter months rather than in the spring and summer.
