1000 Seeds Seedbox Ludwigia alternifolia

Seedbox (Ludwigia alternifolia) is a native North American wildflower prized for its bright yellow blooms and distinctive square seed pods that follow the flowers. Blooming through summer into early fall, it brings a cheerful, natural look to meadows, wildflower plantings, and rain gardens. Its upright stems and vivid flowers also make it a standout in pollinator-friendly landscapes and native plant collections. This plant works well in informal garden beds, meadow mixes, and along pond or stream edges where the soil stays consistently moist. The nectar-rich flowers draw bees and other pollinating insects, while the unusual box-shaped seed capsules add late-season interest and self-sow readily in suitable sites. Easy to grow from seed, it thrives with regular moisture and rewards gardeners with reliable color and texture across the season.
