Helonias

Helonias is a genus of flowering plants in the Melanthiaceae family. It contains only one accepted species, Helonias bullata, commonly known as swamp pink.

Helonias bullata is a rare perennial herb native to the eastern United States. It is found in acidic wetlands, specifically in seepage bogs and acidic swamps, from New York to Georgia. It is characterized by a basal rosette of lance-shaped leaves and a tall stalk bearing a raceme of pink, star-shaped flowers in the spring. The plant reproduces by both seeds and rhizomes.

Due to habitat loss and degradation, Helonias bullata is listed as threatened or endangered in several states. Conservation efforts are underway to protect remaining populations and their fragile wetland habitats. Its specific requirements for acidic, nutrient-poor, and consistently moist conditions make it particularly vulnerable to environmental changes such as alterations in hydrology and nutrient input.

The genus name Helonias is derived from the Greek word "helos," meaning marsh or swamp, referring to the plant's typical habitat.
