Compact and easy to grow, this low-maintenance perennial offers fine, thread-like foliage and pale blue, starry flowers that appear in late spring. Upright and densely clump-forming, it’s ideal for sunny borders or prairie-style planting schemes.
Amsonia 'String Theory' stays smaller than other types, with a tidy, bushy habit. The dark green summer foliage stays clean and healthy and turns a bold golden-orange in autumn, adding seasonal colour. It’s heat and humidity tolerant, copes with some drought once established, and is reliably deer resistant.
Useful for mixed borders, naturalistic planting or low-intervention spaces.
