Hydrangea quercifolia Bartram. Phen: May-Jul. Hab: Native in hammocks, moist forests, also in disturbed areas, thickets, or forests adjacent to urban or suburban areas. Dist: C. and sw. TN, south through w. GA, AL, and MS to Panhandle FL and e. LA; scattered elsewhere as a remnant or escape from cultivation. Boufford & Wood (1977) described a purportedly native occurrence in nw. SC, but it seems possible that this is an escape from cultivation (R. Clark, pers. comm.). This southeastern native is a spectacular garden plant, frequently planted, and sometimes persisting or possible escaping.
