Comments: New foliage is rich green to bronze or purple green; may be damaged by hard frost or freeze. New foliage is purple-bronze, then turning a lustrous dark green. Many branches originate at nearly the same point, resulting in weak crotches that break easily. Train as nearly to a central leader as possible to help reduce the breakage.
