It is hardy to zone 4 and grows naturally throughout the northeast in wetlands and shallow water, preferring partial sun to light shade. When cultivated, arrow arum can make an impressive container plant or a waterside accent. This plant prefers deep, silty, saturated soils with a pH between 3.0 to 9.5. It does well with fertilization in soils with low organic matter. When planted in a fish pond, arrow arum should be trimmed down at the end of the growing season to prevent plant material from decaying in the water over the winter. Otherwise, the arrow arum is low-maintenance. It can be placed in up to 18 inches of water. This native plant is ideal for those looking to attract ducks, pollinators, and other wildlife to a water feature. Their nutrient uptake also helps keep ponds clean. Arrow arum contributes to the natural landscape and encourages visitors like deer, muskrat, rails, and birds.
Arrow arum can be cultivated by seed or by removing offsets from an existing colony.
