A new Amsonia from Proven Winners®, the String Theory Amsonia PP#34419 (Amsonia x 'String Theory') is a soft powdery baby blue, densely-packed, rounded blossom that whimsically dances above the upright vase-shaped slender thread-like foliage of this new perennial cultivar!

Appearing in round clusters just above the foliage, the star-shaped florets bob and wave in the breeze throughout the late spring and early summer weeks. Almost resembling Allium, the bees and butterflies will show up strong for the rich nectar and pollen. The slender stems make String Theory great for cut flowers too!

Also known as Willowleaf, Dogbane, Star-Willow, and Blue Star (Bluestar), Amsonia is native to the Southeastern US and this cultivar brings a world of new interest to the many, already fantastic qualities of these perennials! Hardy throughout USDA planting zones 4 to 9, meaning they are wonderfully cold-hardy and heat-tolerant!

Landscape Application:

String Theory Amsonia is a lower-growing perennial, topping out at 18-22 inch height when in bloom, yet creates drifts 30-36 inches wide. The politely spreading form readily creates seas of soft blue throughout your sun or partially shaded garden beds and borders! Go for a meadow or woodland look without worrying about deer!

A must-have for Pollinator and Cut Flower gardens, these front to mid-garden specimens and accent plants fill Cottage borders and mixed Perennial gardens in sky-blue color and verdant greenery! Add this whimsical Dr. Seuss plant to Children's Gardens and fun informal plantings! Mix with spiral topiary evergreens, Alliums, Corkscrew Rush, Buttonbush, Hollyhocks, Weeping Trees, and lollypop-trimmed Rose Trees for a quirky display.

String Theory Blue Star even pops well in small and large planters!

  • Soft Sky Blue Rounded Flower Clusters & Star-Shaped Florets
  • Vase Shaped Upright Bright Green Thread-Like Foliage
  • Late Spring to Early Summer Bloom Time
  • Pollinator-Friendly!
  • Unusual Cut Flowers
  • Fanciful Specimens, Drifts, Container Accents & Mixed Sun Gardens

#ProPlantTips for Care:

Amsonia is very low maintenance and easy to grow! Provide a well-drained area in full sun or partial sun areas and water them regularly until established. Although Blue Star is adaptable to a little light shade, too much shade will cause these perennials to flop, so please choose its location carefully. It will show tolerance to drought but protect your investment in long periods without rain by providing water and a 3-4 inch deep layer of mulch. The only pruning necessary is to cut the seed heads off in the fall and trim back the foliage in the early spring.

  • Full Sun & Part Sun
  • Well-Drained Soil
  • Moderate Moisture Needs
  • Deadhead In Fall/Prune In Spring
  • Deer Seldom Bother These Perennials

Fat round blue stars and thread-like greenery - choose something fun this year and order the Proven Winners® String Theory Amsonia Blue Star for your landscape! Now available at NatureHills.com!
