Amsonia String Theory

Common Name: Blue Star

People have loved 'Storm Cloud' and we are now pleased to offer a complementing threadleaf Amsonia to the Proven Winners program. '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. We have observed 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.
