The Story
Plant Bio
Penstemon hirsutus is a tough, clump-forming perennial native to eastern North America, characterized by its hairy stems and leaves. It produces spikes of tubular, two-lipped flowers that are highly attractive to native pollinators. As the straight species, this plant offers the authentic genetic resilience and ecological value of a true native. Its soft lavender and white flowers are perfectly adapted for long-tongued bees, making it an excellent choice for wildlife gardens.
