Amsonia hubrichtii (Threadleaf Bluestar) is a unique perennial with narrow needle-like leaves that are soft to the touch. It has light blue flowers, feathery green summer foliage, and golden fall color. The fall foliage color is one of its most valuable features. The Amsonia hubrichtii is a showy perennial that attracts bees and butterflies. It grows into a dense mound and is used in mass planting, rain gardens, or floral arrangements. The Amsonia hubrichtii is native to the Ouachita Mountains in Arkansas and was discovered growing in the wild in the late 1940s. It is commonly known as Bluestar, Arkansas Amsonia, or Hubricht’s Amsonia. 2017 Green Ribbon Native Plant Winner, 2016 Garden Club of America Plant of the Year special recognition, 2014 Pennsylvania Gold Medal Award, and 2011 Perennial Plant of the Year!
