"Leopard's Bane". In spring, many branching stems of large, bright yellow, daisy flowers appear and are continuously produced for weeks on end. The entire plant spreads very slowly via small tubers and is thus also ideal for the wild garden.
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.
