green arrow arum
Peltandra virginica is a plant of the Araceae family known by the common names green arrow arum and tuckahoe. It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba. It is common in central Florida including the Everglades and along the Gulf Coast. Its rhizomes are tolerant to low oxygen levels found in wetland soils. It can be found elsewhere in North America as an introduced species and often an invasive plant.
This is an emergent perennial herb growing from a large rhizome and producing many large leaves. An individual leaf may have a petiole nearly a meter long and a blade half a meter in length. The leaves are quite variable in shape and size, but they are often generally arrowhead-shaped.
The inflorescence bears male and female flowers, as well as sterile flowers. The flower varies from whitish to greenish to yellow. The fruit is a brown berry containing a few seeds within a clear gelatinous pulp. Large number of seeds can accumulate in the soil of wetlands.
