Cultivation Details

HabitAnnual
GrowthFast

A fast-growing plant[1], it succeeds in ordinary garden soils[2] and also in poor soils[1]. It requires a very well-drained soil[1], preferring to grow on a dry sunny bank[3]. A frost tender annual, it does not thrive in areas with hot humid summers[3].

Propagation

Seed - sow early to mid spring in a greenhouse. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant them out in early summer. Alternatively, if you have sufficient seed it is possible to sow in situ during mid spring.
