Stiff bluestar (Amsonia rigida) is a U.S. native that produces clusters of light blue flowers in late spring and rich yellow fall leaf color; 2 to 3 feet tall. The overall effect is something like that of ‘Blue Ice’, but this species is taller and a clump-former rather than a spreader. The plants I collected these seeds from were growing near Arkansas bluestar (A. hubrichtii), so there’s a small possibility that some seedlings may show some intermediate traits. Full sun to light shade. Perennial; Zones 5(?) to 9.
2021-collected seeds sold out. I hope to collect again in late September 2022. At least 20 seeds.
Please read the germination information as well before ordering.
