Genus of 4 species of evergreen succulents from South Africa. Rochea (Crassula) grow best in high light but some tolerate lower light intensity. A well-drained soil is essential. Keep the soil moist when the plants are growing but drier during rest periods. Do not let temperatures drop below 45 degrees. If repotting is necessary do it as new growth commences. Allow the soil to become quite dry after repotting.
