This unique planting is north of the Nut Trees on the west side of the Arboretum. Phase 1 of the Peony Labyrinth installation was completed in fall 2010. The Labyrinth is 10,000 square feet and contains 5 varieties of peonies all donated by former Arboretum Board President Dale Siems of Charles City. Some of those varieties are Paeonia 'Shawnee Chief', 'Minnie Shaylor', Fairbanks', 'Duchess D'Orelans'. More peony varieties will be added during 2011 as well as groundcovers.
