A Native Re-Greening for TreePeople’s Cistern

Park operations director Jim Hardie calls it the “grasscrete circle”—also known as the TreePeople cistern, a 216,000-gallon underground storage tank, where we save rainwater filtered and collected from rooftops and the Parking Grove. For the past four years, the circle has been planted with wildflowers, which look gorgeous but require regular weeding. Jim is excited about a low-maintenance alternative called purple needlegrass—the official state grass of California!
