Swamp-pink is a threatened species throughout its entire range of the eastern USA (from Delaware to Georgia), primarily due to habitat destruction. New Jersey, where today’s photograph was taken, contains both the most and the largest remaining populations (a “stronghold“, partly due to the Pinelands National Reserve). Like yesterday’s alpine-groundsel, the common name suggests its habitat: “…wetland habitats. These include Atlantic white-cedar swamps; Blue Ridge swamps; swampy forested wetlands which border small streams; meadows, and spring seepage areas. The plant requires habitat which is saturated, but not flooded, with water…” (via the Center for Plant Conservation’s fact sheet on Helonias bullata).
This Trillium relative is a herbaceous perennial species. Evergreen leaves grow near the ground in a rosette, so can be hidden and protected by leaf-litter and snow during the winter and early spring. A single flowering stalk is produced, reaching as high as 90cm (3ft.) while in bloom (mid-April to June) and even higher (to 150cm) in fruit.
