'String Theory' (Amsonia)

Our perennials are currently going dormant. The foliage and blooms begin to brown and die back. We provide a hard trim in the greenhouse to support this process. During dormancy, plants go inactive to conserve their energy for the next growing season. This happens naturally as seasons change!
