DistributionThis is a taller, larger-flowered, maritime and near-maritime version of O. fruticosa. Recent work by Sorrie et al. (2018) has demonstrated that it should be treated as a distinct species. NC records are essentially in coastal counties from Hyde and Dare counties southward.

"Se. VA south to e. SC and e. GA" (Weakley 2020)
AbundanceUncommon to infrequent. It is tracked by the NCNHP as Significantly Rare, with a State Rank of S1S2.
Habitat"Sandhills, moist to wet loamy savannas" (Weakley 2020)
PhenologyFlowers and fruits from April to August.
IdentificationSee Sorrie et al. (2018) for the revision paper, along with photos. It differs from the common O. fruticosa by having "Free sepal tips 1-3 mm long, cartilaginous and often arching after the sepals have reflexed; calyx strigose" (Weakley 2020). As mentioned above, it is taller and larger-flowered than O. fruticosa and is found mainly in or near maritime habitats.
