This is truly one of the most impressive plants you can grow in the UK if you can give it room. Candelabras of large mauve flowers open on much-branching white woolly stems which arise from a huge grey spiky rosette in spring.

Sowing Advice

Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
