Positive	Malus2006	On Apr 3, 2008, Malus2006 from Coon Rapids, MN (Zone 4a) wrote: The rarest tree in the plant trade - two are found on the University of Minnesota St. Paul Campus but I hadn't seen them anywhere else.
Positive	Decumbent	On Oct 28, 2006, Decumbent from Cincinnati, OH (Zone 6b) wrote: Exceptional foliage in all seasons, but especially in fall. This tree seems prone to verticilium wilt and therefore needs to be planted in dry soil.
Neutral	nick89	On Feb 6, 2005, nick89 from Tallahassee, FL (Zone 8b) wrote: An intresting small, frequently contorted tree of limestone uplands that is common in some places here and rare to nonexisistent in others. Flowers are not very showy. The second or third largest specimen in Madison County, Alabama resides in the woods behind my house.
Positive	lupinelover	On Jan 13, 2003, lupinelover from Grove City, OH (Zone 6a) wrote: This species grows bigger than the more common purple smokebush. Its leaves are green, its "smoke" is much bigger, more colorful, and persists into winter, giving a long season of interest. Seeds readily germinate when ripe, they can be sown immediately or stored; stratification not needed.
Neutral	smiln32	On Aug 31, 2001, smiln32 from Oklahoma City, OK (Zone 7a) wrote: Grow in average, medium wet, well-drained soil in full sun. Adaptable to wide range of soils, including poor rocky soils, but prefers well-drained, somewhat infertile loams
