Safety & Hazards
None known
Cultivation Details
Requires a well-drained soil and a sunny position[1]. Dislikes acid soils[1]. Tolerates poor soils[1]. Grows well on a sunny wall and is indeed longer lived in such a position[2]. A polymorphic species[3], it is possibly a form of E. asperum[4].
Propagation
Seed - sow spring in an outdoor seedbed. Germination usually takes place within 3 weeks. Plant the seedlings into their permanent positions when they are large enough to handle. If seed is in short supply, it can be sown in spring in pots in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer.
