Once you say the word “bioswale,” it’s sort of hard to stop. Try it. And while you become enamored with the word, we’ll explain what the heck it is and what you should do with it.
Seriously — What IS A Bioswale?
Bioswales are landscape elements designed to remove silt and pollution from surface runoff water. Troughs with gently sloped sides, they’re filled with vegetation, providing a path for water to run through slowly, rather than rushing off into a storm sewer or local waterway.
Storm water runoff picks up all sorts of pollutants and contaminants on its way into storm drains, streams and lakes. The plants and soil in the bioswale slow and clean the runoff before it enters the water table. Properly landscaped, they can be pretty while doing their job at the same time.
What To Plant In A Bioswale
Bioswale plants have to tolerate standing water, but also need to thrive when the water dries up. Each bioswale actually has several growing “zones” with different needs.
The center, and deepest, part of the bioswale prefers plants that love moisture. The middle of the sloping sides prefers wet to dry plants, while the upper rim likes drier types of vegetation.
Native plants — plants that grow naturally or have existed for many years in an area — are great choices for bioswales. Here’s why:
- Native plants love the local climate. Once planted and established, they don’t need extra water or fertilizer.
- Many are deep rooted, so they’ll survive droughts.
- Native plants provide habitat and food for native wildlife. Bees, butterflies, beetles and birds — all important pollinators — love them.
Native Plants Neave Loves
The good news is there are lots of native plants to choose from here in New York and Connecticut, including wildflowers, sedges, rushes, ferns, shrubs and small trees.
Native switchgrass is a good start, and there are several varieties to mix and match. Add some color with sturdy flowering perennials native to this area — maybe sneezeweed, bee balm, Joe Pye weed or milkweed.
For height and structure, consider shrubs and small trees; try winterberry or American hornbeam.
