Swamp White Oak

Seaside Arrowgrass is a native perennial commonly found in wetlands, salt marshes, and moist meadows. It is especially suitable for difficult growing sites. Its dense root system helps stabilize soil, while also providing food, cover, and habitat for small animals within the wetland community.

Seaside Arrowgrass is suitable for shoreline stabilization, wetland restoration, and naturalization projects.

The Swamp White Oak is a medium-sized deciduous tree native to North America. It is commonly found in swamps, lowlands, floodplains, and near streams and lakes. The leaves are two-toned, green on top and silvery-white on the undersides, adding to the visual appeal of this popular shade tree.

In the fall, the Swamp White Oak produces acorns which are an important food source for wildlife. It also provides a habitat for the larvae of many butterfly and moth species, playing an important ecological role. Although its growth is slow in the first few years, once the roots are established, it can achieve faster annual growth.
