In Virginia Magnolia tripetala is a disjunct in the coastal plain. 

 The malodorous flowers of Magnolia tripetala are uniquely associated with this species. The tree is occasionally cultivated. Both filiform and flagelliform trichomes occur on the leaves. Sometimes cylindric trichomes also occur.

The largest known tree of Magnolia tripetala , 15.2m in height with a trunk diameter of 87 cm, is recorded from Bucks County, Pennsylvania (American Forestry Association 1994).
