Swamp-loosestrife thrives in wet, boggy conditions such as pond margins, rain gardens, or consistently waterlogged soils. Plant in part shade to full sun and ensure the root zone never dries out — this is an ideal plant for naturalizing the edges of water features. It produces attractive whorled pink-purple flowers in summer and develops arching stems that can root at their tips.
