For over a year I have been desperately trying to identify this plant seen on a college campus in Waltham, Mass. I think they grounds crew cuts it down for the winter and it grows back ever year. It is mostly green until the fall colors that are shown in the picture. Any assistance from your community would be GREATLY appreciated. Thank you.

It looks very much like Amsonia Hubrichtii, a U.S. native shrub that has needle thin foliage with star-shaped light blue flower clusters in spring and golden fall color. Also called Arkansas Blue Star.
