Narrow Leaf Blue Star (Amsonia hubrechtii)
I believe this plant was discovered by Leslie Hubricht. This blue star has the narrowest, laciest, most threadlike foliage of any amsonia species. The beautiful southern native is truly the best of the blue stars. The sky blue flowers emerge atop the foliage when it emerges in April and continue into May. The deciduous golden fall foliage is stunning! Amsonia hubrichtii makes a clump to 3' tall x 3' wide.
