Cultivation Details
Easily grown in an ordinary garden soil[1]. Prefers a well-drained to dry soil in a sunny position[2]. This species is not hardy in all parts of Britain, it tolerates temperatures down to at least -5°c[2]. A monocarpic species, growing for a number of years before it flowers but then dying after flowering[2]. It is said to produce viable seed in this country[2].
Propagation
Seed - sow in an outdoor seedbed in mid spring[3]. It might be better to sow the seed in the autumn in a cold frame or greenhouse[PFAF]. The seed germinates in 2 - 6 weeks at 15°c[3]. If seed is in short supply we would recommend sowing it in a pot in a cold frame and pricking out the seedlings into individual pots as soon as they are large enough to handle. Plant them out into their permanent positions in late spring of the following year.
