Propagation
Sow fresh seed during spring and it takes 3 to 4 years to come to flower.

Divide the clump from winter to early spring and reduce the foliage by 50%.

Culture
When planting space 50cm (1½ft) apart to form a good clump in two years and is suitable for coastal regions.

Flower: The funnelform flowers have 5-expanding petals with exserted stamens and are up to 50 mm wide (2in). They are arranged in a terminal umbel above the foliage on a long scape appearing from late spring to early summer.
