Propagation
Surface sow fresh seeds from autumn to spring in pots or flats and in cold climates place in a cold frame to germinate. Prick out and pot-up when large enough to handle.

Take soft tip cuttings during summer and place in a protected environment in a well-drained media and apply bottom heat.

Botanic information
Leaf: The dark green sessile spathulate to oblong leaves are up to 35 mm (1⅜ in) long and have an obtuse apex. The texture is slightly fleshy and the leaves are crowded alternately along the stems.

Flower: The small cyathiform flowers have 4-petals with two being larger and slightly exserted pinkish stamens with yellow anthers. They are arranged in a crowded terminal corymb-like raceme that is up to 50mm (2in) wide and appear profusely from the late spring and early summer.

Fruit: The small elliptical siliqua is 2-locular with solitary seeds and is normally removed from the plant to extend the flowering period. The seeds are viable but the plant may be reproduced vegetatively
