Origin and Habitat: Cradock District, Eastern Cape, South Africa.
Description: Rabiea difformis is a low-growing matt-former from South Africa.
Blooming: Supposed to bloom mostly in spring and summer, but seems to bloom almost randomly.
Cultivation and propagation: Rabiea are easy and rewarding plants than can be grown in pots or in the rock-garden. They can be watered year-round, water regularly from spring to Autumn but reduce watering frequency in winter, growth period is early Spring to late Summer, but is a very adaptable species that can grows opportunistically whenever the water availability and growing condition are favorable. Keep them cool, and half-shaded in summer, need full sun or light shade on the other seasons. Potted rabieas look best in a heavy soil and the same is true for plants in a rockery. Requires good drainage.
Frost tolerance: Very frost hardy and grows best where there are cold winters (it is reported to be hardy to at least -18° C if very dry). It is difficult to keep the leaves free of scars and dead leaf-tips, but the abundant flowers hide them.
Remarks: Rabiea has a gorgeous, thick root system and when it is potted up, the plant can be progressively raised over the ground so that some of the roots can be seen and is especially cultivated for their looks. Architecturally it is a real stunner. When the "caudex" shape of the raised roots is adequately in evidence this plant is incomparable. They also tend to grow more "heads" when they are raised.
