Threadleaf bluestar Interesting Notes

"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

Prefers full sun in moist, average or dry soil. Slow to grow at first, but takes off in the second year. Fall color is brightest in full sun. Use in borders, rock gardens, native gardens, cottage gardens or open woodland areas. Best when massed.
