We do not have information on this species, but the following notes are based on the closely related C. solstitialis. Succeeds in ordinary garden soil[1, 200]. Prefers a well-drained fertile soil and a sunny position[200]. Tolerates dry, low fertility and alkaline soils[200]. A good bee and butterfly plant the flowers are rich in nectar[171]. Members of this genus are rarely if ever troubled by browsing deer[233].
Propagation
Seed - sow April in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer. If you have sufficient seed it can be sown in situ in the spring, and an autumn swing in situ might also be worth trying.
