Amsonia hubrichtii

One of the very few perennials known for fall color and a US Native to boot! Threadleaf Bluestar is deserving of a place in every garden. It provides textural beauty, star-shaped flowers, blue blossoms, golden-yellow fall color and is insect, deer, and disease resistant. Fall color is best in full sun, but flowers generally last longer if given some afternoon shade.

Tip: Cut the stems back by about 6" after flowering to prevent flopping.
