'Dark Towers'
Penstemon digitalis
Penstemon digitalis ‘Dark Towers’ brings a bold, modern presence to the perennial border with its deep, glossy burgundy foliage and tall, elegant flower spikes. New growth emerges in rich, near‑black tones, holding its color longer into the season than most dark‑leaved Penstemon selections. In early to midsummer, upright stems carry soft pink, tubular blooms that lighten the plant’s dark base and draw steady pollinator activity. The habit is upright but refined, with strong stems that resist flopping and foliage that maintains its sheen through heat and humidity. Adaptable to full sun and a wide range of soils, ‘Dark Towers’ offers durable performance, long‑season contrast, and a sophisticated color pairing when planted alongside lighter perennials or native grasses.
