Green arrow arum is a native North American aquatic perennial that brings the elegance of wetland ecosystems right into your garden. This Eastern U.S. native thrives in standing water or boggy soils, reaching 18-24 inches tall with showy flowers that bloom from April through June. Hardy in zones 5-9, it tolerates everything from full sun to deep shade, making it one of the most adaptable plants for wet sites. Unlike its aggressive cousin arrowhead, green arrow arum expands slowly into dense, manageable clumps over time.

Green arrow arum is native to the eastern United States, where it has flourished in swamps, marshes, and pond margins for centuries. It grows in standing water up to 6 inches deep without flinching and actually thrives in full shade, a rare trait among aquatic perennials. The plant spreads into expanding clumps at a measured pace, giving you control over its spread without the invasive tendencies of similar wetland plants. Its flowers are genuinely showy, and it asks remarkably little in terms of pest and disease pressure.
Green arrow arum is grown primarily to naturalize wetland gardens and restore native plant communities in rain gardens, pond margins, and riparian areas. Its ability to thrive in standing water and heavy shade makes it invaluable for water gardens and boggy low spots that challenge other plants. It serves as a structural and visual anchor in water gardens, where its showy spring flowers and consistent green foliage add seasonal interest.

“Green arrow arum is a native perennial found throughout the eastern United States, from Maine to Minnesota and south to Florida and Texas, where it is most abundant along the Atlantic coastal plain. The plant has earned common names including bog arum and tuckahoe through centuries of presence in American wetlands. It has proven so adaptable that it has naturalized in parts of California and Oregon, extending its range far beyond its original native territory. In Missouri, it remains primarily confined to lowland areas in the southeastern corner of the state, where wetland conditions mirror its ancestral habitat.”
