Cardwell’s Penstemon (Penstemon cardwellii)
Yet another brilliantly colored Penstemon, P. cardwellii thrives in thin sandy soils, like the northwest side of Mt. St. Helen’s, where we found a stunning display. Rising only a few inches helps the flowers stay out of the wind. What a view it has every day!
Apparently we are not the first to see this mid-summer show:
“Penstemon cardwellii in full bloom. This species grows everywhere in the blast zone of Mt. St. Helens and it’s a sight to see, blooming with red Castilleja species and Lupinus lepidus.” — The Practical Plant Geek
