Please note: The Linnean House conservatory will be closed through December for renovations and repairs. Built in 1882, this structure is the oldest continuously operating greenhouse west of the Mississippi River. Thanks to a gift from the Mabel Dorn Reeder Foundation, the Garden will make improvements such as a new all-glass roof, new windows and more. The Linnean House is scheduled to reopen in Spring 2011.
