Polemonium Pauciflorum 'Sulphur Trumpets'
A delightful form of the North American miniature polemonium or "Jacob's Ladder", Polemonium pauciflorum. Silvery-leaved foliage adorns stems bearing terminal bunches of yellow trumpets, striped in brown, with flared mouths.
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.
