Cultivation Details
Grows well in ordinary garden soil[1, 2], succeeding in most conditions other than boggy soils[3]. It prefers a fertile moisture retentive soil[4] in a sunny position[5, 2]. Dislikes dry soil[4]. An annual or short-lived perennial, this species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[4]. Plants seem to be immune to the predations of rabbits[3]. A good bee and butterfly plant[6].
Propagation
Seed - sow spring in a greenhouse. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer. If you have sufficient seed it would be worthwhile trying a sowing in situ outdoors in mid to late spring.
