Queens Botanical Garden - Where people, plants, and cultures meet

Planted depressions that collect stormwater that runs off surrounding areas. The plant species in bioswales are selected for their ability to tolerate both wet and dry conditions. Rainwater that falls on or flows into a bioswale is retained in the soil (a special soil mixture is used to maximize retention), evaporated, absorbed by plants, and allowed to infiltrate back into the water table.
