| Abundance | Uncommon to infrequent. It is tracked by the NCNHP as Significantly Rare, with a State Rank of S1S2. | |

| Phenology | Flowers and fruits from April to August. | |
| Identification | See 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. | |
