Dark Pentstemon Pentstemon Glaucus
The Dark Pentstemon usually bears wine-colored to nearly black flowers, though sometimes pale yellowish or whitish ones occur. They are ornamented with darker longitudinal stripes and bloom in midsummer in the mountains at 8000-12000 ft. At the higher altitudes the stems are dwarfed and attain no more than 4 in. in height, while ordinarily they grow to 3 ft.
