Green dock is a robust, low-maintenance perennial that grows happily in moist or even waterlogged soils, making it ideal for rain gardens or pond margins. Plant in a sunny to partially shaded location and water consistently, especially during dry spells. It spreads readily so monitor its growth if you wish to keep it contained in a smaller space.
