I collected these seeds from ‘Dark Towers’ beardtongue (Penstemon), which forms dense, evergreen clumps of basal leaves, then produces upright, 2- to 3-foot-tall stems topped with tubular, light pink to pink-tinged white flowers in late spring to early summer. The key feature of this selection is the particularly dark color of the leaves, stems, and seedheads. Seeds from this selection will produce seedlings with a range of foliage colors, from deep purple to purplish green to solid green (as shown in a couple of the photos here). They are all pretty, but if you’re looking for the richest foliage color, keep only the seedlings that are darkest after they have gone through at least one winter. On any of the seedlings the color tends to be darkest in spring to early summer. In mid- to late summer, the leaves may turn green or red-tinged green, but the stems stay deep red, and the developing seedheads will also be deep red.
Harvested in September 2022. At least 20 seeds.
