| Distribution | Throughout the state, and certainly present in all 100 counties.
This is an Eastern species found from MA and eastern OK south to southern FL and eastern TX. Over many of these states, it has been recorded from nearly all counties.
| |
| Abundance | Common and extremely widespread, all across the state. According to the Carolina Vegetation Survey results, this is perhaps the most widely recorded species in survey plots. | |
| Habitat | This vine occurs in most shaded to partly shaded habitats, more so in drier habitats. It favors forest interiors of dry to mesic forests and open woods, as well as thickets. It also occurs in bottomlands, pocosins, and drier swamps, as well as along woodland borders. | |
| Phenology | Blooms from late April to early June, and fruits from September to November, and persistent into winter. | |
| Identification | This is a semi-evergreen or tardily deciduous woody vine, more slender stemmed than many other greenbriers and less inclined to climb high into trees. It often forms tangles over shrubs and saplings. Though its leaf size and shape resembles that of Common Greenbrier (S. rotundifolia), being widely ovate to nearly rounded, and about 3-4 inches long, all one needs for identification is the very glaucous/whitened underside of the leaves. It has many slender prickles along the stems but is not so heavily armed and difficult to walk through as species such as Laurel Greenbrier (S. laurifolia) and Common Greenbrier, owing to thinner and more flexible stems. The fruit are glaucous blue berries. Though observers should quickly see this species in most forests, many plants are young and consist of short stems lying on the ground. As such, it can be easily overlooked, as so much of its presence is as short ground-dwelling vines that have yet to start climbing over shrubs and saplings. | |
