DistributionThe only record of escaped plants is in Alleghany County, collected by D. Poindexter in 2010. Formerly planted on buildings of some campuses, but not escaping.

Native of eastern Asia; in N.A. northeastern states and Ont. south to SC.
AbundanceVery rare.
HabitatIn Alleghany County, vines had escaped to trees of a wooded lot. This is the ivy of the Ivy League -- although in the past 40 years much of it has been removed from buildings to prevent further weakening of brick mortar.
PhenologyFlowering June-August; fruiting September-October.
IdentificationBoston Ivy is a climbing vine with 3-lobed leaves (sometimes fully divided into leaflets), rather resembling Red Maple (Acer rubrum) leaves if not divided into 3 leaflets. The berries are dark blue or black, 5-8 mm wide. From all our grapes it can be told by its white stem pith (vs. brown).
