Established more than 90 years ago by a schoolteacher and naturalist who foresaw the urban sprawl that has made many Minnesota birds and wildflowers rare sights, these 14 acres are a sliver of lovingly tended paradise. All the environments we've paved over are represented: woodland, wetland, prairie, oak savannah. The garden is a living museum of native plants and wildflowers, and one of the few places to see endangered species such as the Mountain Dwarf Trout Lily. Raptors, owls, and songbirds are often spotted along the quiet walking paths where signs mark plants for your edification. Hours: 7:30 a.m. to dusk.
