The genus Crassula is one of the most diverse succulent genera, varying from tiny moss-like annual plants to 2m tall succulent trees like Crassula ovata. Belonging to the Crassulaceae family, there are more than 300 Crassula species of which approx. 150 are found in southern Africa, where they are widespread but concentrated in the semi-arid winter-rainfall areas. The centre of distribution of this genus is in southern Africa, but they extend beyond Africa into Europe, America, Australia, New Zealand and the southern islands. The name Crassula is the diminutive of the Latin crassus which means thick or fat, referring to the fleshy nature of the genus as a whole. This popular genus offers an extensive array of sizes, growing forms and textures making them perfect for landscaping, rockeries, windowsill plants or to be grown in containers. They can also be grown indoors as house plants. Those that make excellent house plants are the glossy leaf varieties. Crassulas, given a rich, well-drained medium will grow fast and luxuriantly.

Crassula capitella, commonly known as Red Flames in English or Aanteelrosie in Afrikaans and synonymously known as Crassula albanensis, Crassula hemisphaerica var. recurva or Crassula impressa, is a South African endemic species found in the Eastern Cape, Free State and Western Cape provinces. Crassula capitella is a stunning succulent that looks fantastic in rockeries and landscape gardens. It is used ornamentally to add a permanent colour in the garden. It is also an excellent indoor container plant. When grown in shade the leaves are bright apple-green all year round. Medicinally, Crassula capitella roots are powdered and used to heal wounds.
