A charming native perennial in the evening-primrose family, Seedbox brightens wet meadows and rain gardens with its delicate yellow flowers in summer and quirky cube-like seed pods in fall and winter.
SeedBox (Ludwigia alternifolia)
•The yellow blooms—though short-lived—are a bright draw for native bees and other pollinators.   
•The unique square seed capsules, which rattle when dry, are a visual and sensory highlight in fall and winter landscape interest. 
•Seedbox thrives in wet or moist soils—found along marsh edges, ditches, and wet meadows—and is a great addition to rain gardens or pond landscaping. It also serves as a host for the Pearly Wood Nymph moth caterpillar (Eudryas unio).
•Light: Performs best in full sun to partial shade. 
•Soil: Prefers medium to wet soils, including acidic, sandy substrates. Ideal for water features, swales, marsh edges, and moist native gardens. 
•Bloom Time: Yellow flowers appear from June through August. 
•Height: Typically reaches 2–3 ft tall; occasionally up to 4 ft.   
•Growth Habit: Multi-branched perennial; blooms repeatedly along stems; seed capsules follow blooming and persist into winter.
