Propagation
Sow fresh seeds during early spring in flats and prick out when large enough to handle.  Plant out after the frost period has ended and space large types 350 mm (14 in) apart and dwarf types 200 mm (7¾ in) apart. 

Take soft tip cuttings in early summer and place in a protected environment.

Culture
Young plants may be pruned to form a bushy habit and spent flower heads should be removed to encourage a longer flowering period.  During autumn healthy plants may be cut back hard, and encourage through cultivation to regrow and flower in the following year.
