Quick Overview:

‘String Theory’ can be described as a compact version of the industry standard Amsonia hubrichtii. The compact habit is covered with light periwinkle blue flowers in late spring, flowering later than ‘Storm Cloud’. While other Amsonia can often display chlorotic leaves, ‘String Theory’ displays healthy dark green leaves throughout the summer. It exhibits the same brilliant golden orange fall color as you would expect from A. hubrichtii.  This easy care, heat and humidity tolerant, deer resistant perennial is an excellent choice for gardeners looking for low maintenance or native perennials.

Description

Easily grown in average, medium, well-drained soil in full sun to part shade. Best fall foliage color usually occurs in full sun, but flowers generally last longer if given some afternoon shade in hot sun areas. Stems tend to open up and flop in too much shade, however. Consider cutting back the stems by about 6″ after flowering to help keep stems upright and to shape plants into a nice foliage mound.  (Courtesy of Missouri Botanical Gardens Plant Finder)
