Davidson's Penstemon (Penstemon davidsonii)

2.50

Also known as Davidson’s Beardtongue, this is similar to its cousin P. cardwellii, but with much smaller leaves and a different shade of similar flower. P. davidsonii forms a dense mat of delightful, tiny, leathery leaves which give rise to tubular blue-purple blooms. This species occurs in subalpine and alpine areas, on rocky, well draining soil, although I’ve personally found it to be pretty adaptable. In any case, it is an excellent choice for rock gardens. It prefers sun, but will tolerate some shade. It is drought tolerant and attractive to pollinators. There is some debate about the need for stratification, but I would be safe and sow these in fall or refrigerate 30 days minimum.
