GENUS INDEX

GENUS CODE: HYDRA
GENUS SCIENTIFIC: Hydrangea
GENUS AUTHORITY: L.
GENUS COMMON: Hydrangea
GENUS SUMMARY: A genus of about 45 species, shrubs and lianas, of e. North America and e. Asia. Molecular analyses have long suggested that Hydrangea as usually interpreted is polyphyletic (Soltis, Xiang, & Hufford 1995; Samain, Wanke, & Goetghebeur 2010) and should be circumscribed more broadly to include other genera in tribe Hydrangeeae that are phylogenetically embedded (including, in our area, Decumaria); this approach has been further developed and formalized by De Smet et al. (2015), an approach followed here (generic and sectional circumscriptions follow De Smet et al. 2015). See Dirr (2004) and van Gelderen & van Gelderen (2004) for information on cultivated hydrangeas.
GENUS IDENTIFICATION: Identification notes: Hydrangea barbara is readily distinguished from the other opposite-leaved, woody vines in our flora (Gelsemium, Trachelospermum, Lonicera, Bignonia, Campsis, and Clematis) by its leaves (simple, ovate, and usually serrate) and climbing structures (adventitious roots).

FAMILY INDEX

FAMILY CODE: HYDRAN
FAMILY SCIENTIFIC: Hydrangeaceae
FAMILY AUTHORITY: Dumortier 1829
FAMILY COMMON: Hydrangea Family
FAMILY SUMMARY: A family of about 17 genera and 190-220 species, trees, shrubs, vines, and herbs, primarily north temperate. As here interpreted, the family Hydrangeaceae includes two well-marked groups, the Hydrangeae (including Decumaria and Hydrangea) and the Philadelpheae (including Deutzia and Philadelphus). This group has been shown by molecular research to be unrelated to the Saxifragaceae, and to have its closest affinities to the Loasaceae, Cornaceae, and Nyssaceae (Xiang et al. 2002; Soltis, Xiang, & Hufford 1995; Morgan & Soltis 1993).
FAMILY REFERENCE: Freeman in FNA (in prep.); Spongberg (1972); Soltis, Xiang, & Hufford (1995); Morgan & Soltis (1994); Xiang et al. (2002); Hufford in Kubitzki (2004).

HORTICULTURAL
Plant Sale Text: Oakleaf hydrangea is the showiest of the North American hydrangeas. This large shrub has sizeable panicles of white flowers which fade to pink and then brown after pollination. The spent flowers can be used in flower arrangements. Fall colors range from orange, yellow, red to burgundy and surpasses that of the oaks. For showy fall colors make sure your plant receives sun for the better part of the day with shade in the latter part of the afternoon. If you wish, cut the plant back in winter to control its size.

USDA PLANTS DATABASE

USDA Symbol: HYQU3
USDA Common Name: Oakleaf Hydrangea
Native Status: L48 (N)
Distribution: USA (AL, DC, FL, GA, LA, MS, NC, SC, TN)
Duration: Perennial
Growth Habit: Shrub

WEAKLEY FLORA

SCIENTIFIC NAME: Hydrangea quercifolia
COMMON NAME: Oakleaf Hydrangea
SYNONYMY: [= C, F, FNA, G, K, S, WH3]
PHENOLOGY: May-Jul.
HABITAT: Native in hammocks, moist forests, also in disturbed areas, thickets, or forests adjacent to urban or suburban areas.
COMMENTS: 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) describe a purportedly native occurrence in nw. SC, but it seems more likely to be an escape from cultivation (R. Clark, pers. comm.). This southeastern native is a spectacular garden plant, frequently planted, rarely escaping or persisting.
