Why We Grow It
Why We Grow It
River Locust is an ideal choice for food forests and ecological restoration projects due to its ability to kickass in any environment. Its nitrogen-fixing abilities improve soil fertility, while its dense root system stabilizes soil and prevents erosion. The shrub provides forage and shelter for pollinators and wildlife, enhancing ecosystem health. Its resilience in poor soils and flood-prone areas makes it a valuable addition to integrated farmsteads and other perennial projects.
How the Plant Grows
How the Plant Grows
River Locust grows as a multi-stemmed, deciduous shrub with a rounded form. It leafs out in spring with pinnate, feathery leaves that provide a lush, green canopy. By late spring to early summer, it produces dense spikes of small, purple flowers that give way to seed pods in the fall. This shrub grows rapidly, establishing itself in difficult soils and spreading through suckers to form dense thickets.

Additional Info
Native to North America, the River Locust is used in stabilizing riverbanks and preventing erosion. Its eye catching, fragrant purple flowers are a magnet for pollinators, while its ability to fix nitrogen enriches the soil for neighbouring plants. Commonly used in agroforestry and restoration projects, this plant provides habitat for wildlife and serves as a nurse plant for young trees in reforestation efforts.
The River Locust is a fast-growing, nitrogen-fixing shrub that excels in challenging conditions. Perfect as a companion plant for larger food producing perennial trees, this fast growing plant provides erosion control, soil improvement, and pollinator support. Its fragrant purple flowers attract bees and butterflies, making it a standout for any sort of sustainable land development.
