2011 Perennial Plant of the Year

Amsonia hubrichtii grows 36 inches tall and 36 inches wide in a mounded form. This hardy perennial grows in hardiness zones 4 through 9 and is a versatile North American native.


Amsonia offers a variety of features throughout the seasons. From late spring to early summer, two- to three-inch wide clusters of small, light blue, star-shaped flowers are borne above the ferny foliage. The alternate-arranged leaves are bright green in spring and summer, but turn a bright yellow-golden color in fall.

• Light – Plants thrive in full sun to partial shade
• Soil – This plant performs best in average, moist well-drained soil but tolerates less moisture. Once established, it can tolerate drier conditions.
• Uses – This perennial for the seasons is an asset in borders, native gardens, cottage gardens, or open woodland areas. It is best when massed. Arkansas blue star is attractive when mixed with ornamental grasses and plants that have attractive seed heads.
• Unique Qualities – Light blue flowers in spring are followed by marvelous foliage in summer. Golden-yellow fall color is second to none among herbaceous perennials.
• Hardiness – USDA Zones 4 to 9

I do not have this in my garden but I have a dozen on order to put a couple in my gardens and share!  I am anxious to watch this perform through the growing season and to see the fall coloration.
