A fascinating plant from Sicily. Large violet blue flowers are produced all summer, followed by remarkable, enormous corkscrew seeds which are commercially used for making hygrometers (to measure dampness) - wet one and watch what slowly happens!
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.
