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.
