  • Broadleaf deciduous shrub, narrow columnar habit, to about 5-7 ft tall and 2-3 f wide (1.5-2.1 × 0.6-0.9 m). Freely branching.   Narrow, linear undulate foliage which gives the plant a feathery appearance.  Reportedly it produces few fruit and its seeds have low viability, hence non-invasive. 
  • Hardy to USDA Zone 3
  • Very adaptable, best with well-drained soils. Pruning seldom needed. Can be used as a narrow hedge or accent specimen.
  • Selected by Ronald Williams of Green Bay, Wisconsin.  It originated from a chance cross-pollination in 1989 of the Rhamnus frangula ‘Columnaris’.  US PP 14, 791.
