Penstemon Hirsutus 'Blue Foam'
This is a lovely bright form of this species from the mountainous western states of the USA, where it decorates the hillsides with compact clumps of white-throated, pale purple, tubular flowers in spring and early summer.
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.
