Broadleaf, deciduous, dwarf tree, variable habit (more than one clone?), but usually much wider than tall.  It may reach a height of 10-15 ft  (3-4.5 m) tall.  A broad dome of dark foliage on a short trunk, sometimes referred at a Parasol Beech.  It has twisted and partly pendulous branches which carry normal reddish purple leaves that turn bronze in fall.  Its short stature and broad, compact branching creates winter interest.
Best in sun on well-drained rich soil with regular watering.
