Amsonia 'String Theory' PP34419 CPBRAF (25) Bare Root Plants
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.
Amsonia thrives in most gardens with little care. It is low-maintenance, easy to grow and trouble-free. Plant it in full sun or partial shade and moist soil of average fertility. If grown in too much shade or very rich soil, its habit will be open and floppy. This plant grows fairly large but it will not need to be divided for many years. Cutting the stems back to within 6-8" of the ground after flowering will result in fuller growth.

Arrived well packaged with no damage. Good amount of roots, and growth has been healthy so far just a few weeks after planting. Highly recommend for mass planting projects.
