Cultivation details.
Prefers a moderately good soil and some shade. Plants usually self-sow freely and can be invasive, especially when grown on old walls. They succeed both on dry-stone walls and on old mortared walls.

Propagation Seed - surface sow March to June in a cold frame and do not exclude light. The seed usually germinates in 2 - 4 weeks at 18 oC. 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. Division in late spring. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
