100 Seeds Great Water Dock Rumex orbiculatus Wetland Perennial

Great Water Dock (Rumex orbiculatus) is a robust perennial native to North American wetlands, known for its tall architectural presence and broad, lance-shaped leaves that emerge with reddish veining. It produces dense whorls of small greenish flowers along sturdy upright stems in summer, followed by reddish-brown seed clusters that persist into fall, adding vertical interest to pond margins and rain gardens.
This species suits naturalized plantings, water gardens, and restoration projects where a large clumping accent is desired. It thrives in consistently moist to shallowly submerged soils and grows vigorously once established, providing cover along pond edges and stream banks.
