Amsonia in first summer of growth

 

Glenda Bosley  a.k.a “groundhog”

 

Amsonia hubrichtii is an underused, low maintenance perennial that is native to North America and was named Perennial Plant of the Year  in 2011.

I have grown this wonderful perennial in a few gardens.  Arkansas Blue Star adds interest and contrast to the garden from early spring until snowfall.  This picture is shortly after planting in a garden that was requested to be created where 90% of the plant material was to be native or edible.

A little known perennial that is long-lived and can tolerate neglect once established.

The finely textured foliage, which is feathery in appearance, adds a unique contrast to the landscape during the spring and summer when bright green and then turns an outstanding bright yellow-golden colour in the fall.

  • Grows as an upright bushy clump that is mound shaped.  Similar appearance to a small shrub.
  • Grows to a height and width of 36 inches.
  • Grows best in full sun or partial shade.  Stems may grow floppy if grown in too much shade.
  • Prefers an average, well-drained, rich, moist soil, but becomes drought tolerant once established within a few years.
  • From May to July this Amsonia produces wide clusters of small, light blue, star-shaped flowers above the foliage.
  • The stems and foliage contain a milky sap, which makes it unappealing to deer.
  • Combines well in the landscape with Echinacea, Liatris and Ornamental Grass.
