This Bioswale was constructed to gather and utilize stormwater runoff. I planted a bioswale a few years back, for the purpose of gathering runoff from an alley where we had no storm drains. The plants I used, Redosier Dogwood bushes and 2 White Birch trees,  absorb the excess runoff and continue to utilize the water nicely to create a  beautiful  corner view. Feel free to share your “bioswale” experience or photos.
