Estimated Native Range

Summary

Sagittaria graminea, commonly known as Grassy Arrowhead, is a deciduous perennial herb that thrives in wetland habitats such as marshes, shallow ponds, and wet woods. It is native to the Eastern and Central United States and Southeast Canada, where it contributes to the biodiversity of aquatic ecosystems. This plant typically grows to a height of 2 feet (0.6 meters) and spreads 1-2 feet (0.3-0.6 meters). The foliage is grass-like, providing a textural contrast in water garden settings. Grassy Arrowhead produces small, showy white flowers with three petals each, blooming in the spring and fall, which are attractive to pollinators such as bees and butterflies.

Grassy Arrowhead is valued for its ability to naturalize in wetland gardens and is often used in rain gardens, pond margins, and as a water purification plant due to its filtration capabilities. It is easy to maintain, requiring minimal care once established. In cultivation, it requires full sun to part shade and thrives in aquatic environments or soil that is consistently moist to wet. It is not particular about soil type as long as the soil is saturated. While it is a beneficial native plant in its natural range, Sagittaria graminea can be potentially invasive in regions outside its native habitat. Gardeners should consult local regulations before planting to ensure it is not a threat to local ecosystems.CC BY-SA 4.0
