Few perennials have ascended from horticultural obscurity to stardom as rapidly as Ozark bluestar (or Hubricht's bluestar or whatever -- it hasn't really settled on a common name). And with good reason. With its substantial stature, airy threaded foliage, pale blue late-spring flowers, and amber-yellow fall color, it has "architectural perennial" written all over it. Not literally -- that would sort of mess up the look. It's equally useful planted singly or in masses.
Full sun to light shade; most soils; drought-tolerant; 3'x3'; late spring bloom. Zone 5.
Native to south-central US
Propagated from plugs; deep 3.5-inch pots
