Cultivation details
Prefers a dryish well-drained sandy loam and full sun[1, 200]. Heavy clay soils may induce winter rots[200]. Succeeds on poor soils[200]. The flowers open in the evening, they are richly scented and are very attractive to moths[4]. The seeds are a good food source for birds, especially finches[200]. The plants of this species are of hybrid origin and usually mutate freely[1]. Usually self-sows freely if in a suitable position[K].
