Crassula perforata 'Variegata' or String-of-Buttons is a variegated form of Crassula perforata, which is native to South Africa. It is evergreen, a fairly fast growing succulent plant. The leaves are connate-perfoliate, ovate to less than 1 inch (2.54 cm) long. In nature and in containers the plants will reach up to 2 feet (0.6 m) tall by 3 feet (0.9 m) wide. The variegated leaves are gathered at the top of the plant and the lower leaves lose their variegations. It is a very attractive plant whether grown in containers or in the landscape. Plants are hardy in USDA zone 9-11.
Blooming: The plants bloom in spring with pale yellow inconspicuous flowers.
Culture: Crassula perforata 'Variegata' do best in full sun to partial shade with a well drained soil mix. In the greenhouse, we use a soil mix consisting of equal parts of loam and sand with small gravel added to ensure good drainage. Although the plants are very drought tolerant, they tend to grow better when they are watered when the soil is dry to the touch. We fertilize the plants only once during the growing season using a balanced fertilizer diluted to 1/2 the strength recommended on the label. When used as a bedding plant here in Oklahoma, it is best to plant them where they are protected from the very hot west sun. During the winter months, water is restricted to only enough to keep the leaves from shriveling.
Propagation: Crassula perforata 'Variegata' is readily propagated from cuttings taken any time of the year.
