Scarlet Bugler Penstemon
Scarlet red flowers adorn straight, upright reddish/purple stems that can reach 4'. Gracing the Rockies in June and July, this beauty has no problem growing up high. Long lasting flowers grow out of sandy, rocky road cuts, amongst rocky crevices and along roadsides. Can take drought conditions although if there is no snow in winter, water plants once a month.
Plant in fall or moist-stratify for 1-2 months. Barely cover the seed. No chocolate cake soil! This plant likes it lean - full sun is best but I see it with some shade along forests.
