Bladder-senna is a fast-growing deciduous shrub valued for its cheerful yellow pea-like flowers and distinctive inflated seed pods. It tolerates poor, dry soils and is an excellent choice for sunny, low-maintenance borders or erosion control. Prune back hard in early spring to keep it tidy and encourage vigorous new growth.
