10 Seeds Eastern Bluestar Amsonia tabernaemontana
Eastern Bluestar (Amsonia tabernaemontana) is a hardy herbaceous perennial grown for its clusters of soft blue, star-shaped flowers that appear in late spring and early summer. Plants form upright, bushy clumps of narrow green leaves that turn golden yellow in autumn, adding multi-season interest to borders and naturalized areas. It is a dependable, low-maintenance selection for temperate gardens.
In the landscape it works well in perennial borders, meadow plantings, pollinator gardens, and woodland edges. The foliage provides a soft, fine texture that contrasts nicely with bolder leaves, and the seed-grown plants establish readily in average, well-drained soils.
