Penstemon Davidsonii Menziesii
A very desirable plant, with dense, compact, spreading mats of tiny green leaves carrying heads of large violet snapdragon flowers in early summer. It looks good whether trailing over the edge of a stone trough or in a selected spot on the rock garden in sun and well-drained soil.
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.
