- Description
-
Stenanthium gramineum, or feather bells, is an herbaceous perennial wildflower in the trillium family (Melanthiaceaea). The plant displays small white flowers in a large cluster from June through September. It is native to the southeastern United States and often found in open, rocky woods, wet meadows, pond edges, and sandy bogs. The fragrant flowers attract bees and the foliage is regularly seen as ornamental. The epithet means "grassy."
Feather Bells tolerates average soil, but performs best in slightly acidic, well-drained soil, rich in organic material. Except for deep shade, it can be grown under any light condition; however, the best flower performance occurs in full sun with supplemental watering to keep the soil consistently moist. It enjoys a long blooming period of 6 weeks, or more, beginning mid to late summer and possibly extending until frost.
Mature clumps can be divided while dormant or in early spring, but it is best propagated from seed. Although naturalizing, this is not an aggressive species.
