Seedbox (Ludwigia alternifolia)
Easily grown in average, consistently moist to wet soils in full sun. Tolerates light shade. May self-seed in optimum growing conditions.
Ludwigia alternifolia, commonly called seedbox or rattlebox, is a multi-branched, yellow-flowered perennial of the evening primrose family. It typically grows to 2-3' (4') tall on reddish-tinged stems clad with short-stalked, sharply-pointed, lance-shaped, deep green leaves (to 4" long).
Common names of seedbox and rattlebox are in reference to the interesting box-like seed capsules which, when mature, will rattle when shaken.
