Acute Willow
Seaside Arrowgrass

Acute Willow is a very fast growing small tree that can reach growth rates of up to 6 feet per year. It's a great choice for developing a quick, hardy shelterbelt, windbreak, or privacy screen.

Acute Willow will grow multi-stemmed but can be pruned to a single stem for a smaller footprint. It prefers moist areas and requires almost no maintenance.

Willows are important to native pollinators each spring as they have higher amounts of pollen and nectar early each growing season when other food sources are scarce.

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.
