The Japanese drumming group Mu Daiko performed Friday at the grand opening of the Ordway Gardens, a $2.8 million building and landscape addition at the Marjorie McNeely Conservatory at Como Park.

The new space includes 2,267 square feet of interpretive exhibit and display space, and a 2,850-square-foot outdoor terrace. The new wing means the conservatory’s bonsai collection can be exhibited year-round, and will provide year-round views into the Japanese Garden, which is closed in winter.
