Product Description
Amsonia 'String Theory' PP34419 CPBRAF (4) 1-gallons
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.

Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.

Plant information and care is provided in the Overview section, Plant Genus Page and general information is provided in the Planting Care & Guides. Additional questions can be asked on each Plant page.
Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!
