Cultivation and Propagation: Bergeranthus 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 favourable. 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 -12° C if very dry). It is difficult to keep the leaves free of scars and dead leaf-tips, but the abundant flowers hide them.
Propagation: Cuttings or (rarely) seeds.
