1000 Seeds Seedbox Ludwigia alternifolia Native Wildflower Yellow Bloom Wetland Rain Garden

Seedbox, botanically known as Ludwigia alternifolia, is a North American native wildflower valued for its bright yellow blooms and distinctive square seed capsules. A member of the evening primrose family, this moisture-loving species brings cheerful color to wet meadows, rain gardens, pond margins, and naturalized areas, and its nectar-rich flowers draw bees, butterflies, and other pollinators through the summer season.
Grown as an ornamental and habitat plant, Seedbox performs best in consistently moist to wet soils and full sun, where it forms upright stems with lance-shaped leaves and four-petaled golden flowers. Blooming from mid to late summer, the flowers give way to unique cube-shaped capsules that hold the small seeds. It works well along streambanks, in bog or rain garden plantings, and in pollinator gardens, and it can be started indoors or sown directly where conditions stay damp. Allow spent blooms and capsules to remain for seasonal interest and self-seeding.
