Support the Flora of the Southeastern US
2024 has been a banner year for making the best flora we can imagine. We've created:
- Keys with embedded images of diagnostic features
- Clickable glossary terms with illustrated definitions
- FloraQuest: Carolinas & Georgia mobile app
- Heliophily and Wetland Statuses
- Direct links to Flora of North America
- 17,730 new high quality diagnostic photos and counting
With financial support from people like you, we are aiming even higher in 2025. Together we can accomplish all this: Vote on our 2025 priorities
- Add Global Conservation Ranks (GRanks) vote
- Professional graphic keys (polyclaves) to individual families/genera vote
- 2 new FloraQuest apps: Florida & Mid-South vote
- Image overlays highlighting diagnostic characters with arrows vote
- iNaturalist integration in FloraQuest vote
We've set a goal of recruiting 200 ongoing supporters to donate $15 or more each month in 2025. Please help us reach this goal and make next year's flora even better:
| Family | Scientific Name | Common Name | Habitat | Distribution | Image |
|---|---|---|---|---|---|
| Hydrangeaceae | Hydrangea arborescens | Smooth Hydrangea, Northern Wild Hydrangea, Sevenbark | Forests, especially around rock outcrops and along streambanks. | NJ, s. NY, OH, IN, IL, MO, and se. KS south to e. NC, c. SC, c. GA, Panhandle FL, s. AL, LA, and OK. |  |
| Hydrangeaceae | Hydrangea barbara | Climbing Hydrangea, Woodvamp, Decumary | Swamp forests and bottomlands, moist forests in the mountains. | Se. VA south to FL and west to LA, s. AR, and e. TX (Singhurst, Keith, & Holmes 2005), inland to nw. SC, se. TN, and w. TN. | |
| Hydrangeaceae | Hydrangea cinerea | Ashy Hydrangea, Southern Wild Hydrangea | Rocky forests and rock outcrops, roadbanks, perhaps strictly or mostly associated with mafic or calcareous rocks. | Sw. NC, c. IN, c. IL, and c. MO south to n. SC, sc. AL, and c. AR. |  |
| Hydrangeaceae | Hydrangea macrophylla | Bigleaf Hydrangea, Mophead Hydrangea, Hortensia | Disturbed areas, suburban woodlands. | Native of Japan. Reported for AR (Serviss et al. 2017). | |
| Hydrangeaceae | Hydrangea paniculata | Panicle Hydrangea | Persistent after cultivation at old home-sites, sometimes appearing naturalized. | Native of e. Asia. |  |
| Hydrangeaceae | Hydrangea quercifolia | Oakleaf Hydrangea, Greybeard, Old Man's Beard | Native in hammocks, moist forests, also in disturbed areas, thickets, or forests adjacent to urban or suburban areas. | 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. |  |
| Hydrangeaceae | Hydrangea radiata | Snowy Hydrangea, Silverleaf | Rocky forests and rock outcrops, often common and conspicuous on roadbanks. | A Southern Appalachian endemic: sw. NC (in the valley of the French Broad River and to its southwest), nw. SC, ne. GA, and se. TN, with outliers (perhaps escaped from cultivation?) in Stokes County, NC and Calhoun County, SC |  |
