Shorter, more compact hybrid of Amsonia hubrichtii (Threadleaf Bluestar). Better resistance to chlorosis, densely branched clean habit, the same excellent orange-yellow fall color as it's parent.
Flowers above the foliage with pale periwinkle blue flowers. Leaves are narrow, linear and needle-like. Heat and humidity tolerant.
Blooming Time : about mid May for about 3-4 weeks (depending on your climate)
Size: 18-22" tall x 32-36" wide dense clumps
USDA Zones: 4 to 9
Culture: full sun to half shade, average soil to other soil types, including clayish soil, adaptable. Best around neutral of ph 7.

Deer/Rabbit Resistant: yes / yes
Attracts Butterflies or Pollinators: possibly yes(but it usually blooms before the butterflies hatch) / yes
Attracts Hummingbirds: no
Pot Size: round Proven Winner quart 4.25" x 5" deep
Plant Combinations: For flower beds, naturalistic plantings, deer and rabbit resistant plantings, meadow and pollinator gardens. Goes very well with most of the common perennials, grasses and wildflowers.
The structure is very fine and the whole look regular, so the best combos include plants with more coarse-rough structure, large flowers or with somewhat more natural look. So good combinations can be achieved for example with Alchemilla mollis, Anemone hupehensis (japonica), Chelone, Geranium 'Rozanne', Hemerocallis (daylily), herbaceous Hibiscus, Iris, Leucanthemum, taller Monarda, Paonia, Persicaria, Phlox paniculata and hybrids, Physostegia, Salvia nemorosa, Silphium, Stachys, Tradescantia, bigger-leaved Vernonia or Veronicastrum.
The blue flowers of this Amsonia will nicely contrast with yellow or cream cultivars of Aquilegia, Aquilegia canadensis, yellow Baptisia, yellow Irises, yellow peonies or Zizia.
Suitable grasses include Calamagrostis, Carex,Pennisetum, Molinia or Panicum.
