Acer pentaphyllum - MO or retail?

Deciduous and rare Chinese maple, with deeply cut, 5-lobed leaves - very un-maple-like and very graceful and charming, leafing out late in spring and showing off in autumn with bright colors. This delicate tree, nearly extinct in the wild, grows slowly, reaching perhaps 15 ft over a long time. A lovely addition to a garden of any size in sun to part shade and well-drained soil. Requires regular summer moisture. Frost hardy in USDA zone 7.
