Swamp Pink

Helonias bullata (hel-OH-nee-us bul-LAY-tuh)

Family: Melanthiaceae Native Herbaceous (1-3 ft)

Swamp pink is an herbaceous perennial wildflower in the trillium family (Melanthiaceae). It is native to the Atlantic coastal states from GA to NJ, including NC. The species epithet means "blistered or puckered," and perhaps refers to the texture of the leaves when dried. Swamp Pink was federally listed as a threatened species in 1988 due to the loss of its forested wetland habitat through encroaching development, sedimentation, pollution, and wetland drainage. This plant is currently classified as a Federally and NC Threatened species. The swamp pink is an obligate wetland species, meaning it requires an area that is perennially saturated but not flooded, with the water table at or near the surface and fluctuating only slightly during spring and summer months. It is found naturally in bogs, under shrubs, and in peaty soil. It has thick rhizomes that store energy for the plant. Swamp pink is a beautiful and unique perennial wildflower, one of the first to bloom in the spring with a bubble gum pink flower clusters that appear in early March and last through May. The stalk is topped by a 1"-3" long cluster of 30 to 50 small, fragrant, pink flowers dotted with pale blue anthers. Insects, Diseases, and Other Plant Problems: No significant problems
