Amsonia hubrichtii

Threadleaf Blue Star
ARKANSAS BLUE STAR


Herbaceous Perennial

"In late spring and early summer a constellation of powdery sky-blue flowers burst forth atop the fine feathery foliage of Amsonia hubrichtii. Thread-leaf bluestar has thin, light green needle-like foliage. As these long-lived and reliable plants mature in midsummer they give the impression of billowing clouds melding with the surrounding landscape. One of the best perennials for fall color, it shines with a radiant bright yellow color before going dormant for the winter. This long lived perennial prefers a rich well-drained soil and regular summer watering. Plant it in full sun for the best flowering and brightest fall color. Be patient with new young plants, often they can look a little straggly and forlorn and may take a few years to fill out. To help plants establish give them some space to minimize competition. Once they mature they will be long lived and robust, full specimens." —Great Plant Picks
