Olbrich's beautiful and environmentally friendly Rain Gardens are landscape features used to control water run-off. During a storm, rainwater collects in the gardens where it is gradually absorbed into the soil to help recharge our ground water. Rain gardens minimize the volume and improve the quality of water entering conventional storm drains and nearby streams.
The Rain Garden next to the Rose Garden features a serpentine boardwalk, made of recycled plastic bags, that allows visitors to walk through the flood-tolerant plants.
Olbrich’s newest Rain Garden, near the Herb Garden, is home to many moisture-tolerant native plants.
