Description

Green Arrow-arum is a flowering, herbaceous perennial, aquatic plant in the arum family native to Canada and eastern and central North America. It is commonly found in freshwater bogs, ponds and marshy areas. The large leaves are variable in shape and size, but they are often generally arrowhead-shaped. They grow from a large submerged rhizome and are tolerant of low oxygen water conditions. The greenish-white or yellow flowers appear in spring in a spadix, hidden behind a 8 inch light green spathe. The plant is deciduous in the northern range and evergreen in the far south. The genus name comes from the Greek words for a shield and man (andros). The species name means of Virginia.

Green Arrow-arum requires wet, acidic, consistently boggy, soils (muck containing organic matter, sand, or peat) in fresh water up to 6 inches deep. The acidic soil should have a mean pH of 4.8 (range 4.0 to 6.0). It does best sited in full sun to part shade, but will tolerates full shade.You can grow it in shallow ponds with earth at the bottom or in large containers or tubs. 

If conditions are favorable, Green Arrow-arum can form dense colonies of expanding clumps over time. However, it does not colonize aggressively.

Clemson University Home and Garden Information Center has a factsheet on "Shorescaping Freshwater Shorelines" including information on planting Green Arrow-arum.
