threadleaf bluestar Interesting Notes

The Perennial Plant Association's 2011 Perennial Plant of the Year™

"The foliage of A. hubrichtii is feathery, like A. ciliata, but leaves are a little wider and longer. The flowers are light blue and are almost white as temperatures warm up in spring. The early flowers are easily visible, but the foliage tends to cover the later opening flowers. The narrow foliage (less than 1" wide) makes a marvelous display throughout the season, and the golden-yellow spectacle in the fall is second to none among herbaceous plants. Plants have been difficult to locate in the past, but the garden attributes have been recognized by more nursery people, and plants are much more available. Well worth growing." - Allan Armitage, Herbaceous Perennial Plants
