The Oudolf Garden Detroit on Belle Isle is a 2.5-acre perennial garden featuring 32,000 “hearty perennials and grasses,” in front of the Nancy Brown Peace Carillon. Volunteers raised $4.7 million to install and endow it, overcoming record flooding in 2019 and working through the COVID-19 pandemic. It opened on Aug. 28, more than five years after The Garden Club of Michigan sent a letter to Dutch master garden designer Piet Oudolf, which set the project in motion.
