Official Minnesota State Flower

Pink and White Lady's Slipper

(Cypripedium reginae)

Adopted in1893.

The pink and white lady slipper, Cypripedium reginae,  was adopted as the state flower in 1893. It is one of Minnesota's rarest wildflowers. Thriving in swamps, bogs, and damp woods, they grow slowly, taking 4 to 16 years to produce their first flower. Sometimes they live for 50 years and grow four feet tall. They bloom in late June or early July. It is illegal to pick the lady slipper.

In 1990, Governor Rudy Perpich declared 81 miles of Highway 11 a Minnesota Wildflower Route, in honor of the hundreds of thousands of Showy Lady's-Slippers growing within sight of the road. The town of Williams held a celebration of the event, which became an annual Wildflower Day. The state put up signs depicting the Showy Lady's-Slipper to mark the route, and pledged to expand the highway only to the south, protecting the masses of Showies Lady's-Slippers on the north side of the road.
