Peony Day in Rosendale, Wisconsin is celebrated the first weekend in June. Sisson’s Peony Gardens were begun in 1928 by Wilbur Sisson and are now on the National Register of Historical Places.
A short drive from Madison, these magnificent gardens are a sight to behold. Take Highway 151 North, and take the Rosendale/Oshkosh Highway 26 exit. There on Main Street you will easily be able to find the peony gardens, just look for the flowers and blue windmill. The entrance gate and blue windmill was built from fieldstone taken from a local church.
The peony gardens are now owned by the Rosendale Historical Society who have taken the responsibility of maintaining the gardens to a state of perfection.
There is an article on the peony garden posted at the Wisconsin Historical Society website http://www.wisconsinhistory.org that is quite interesting.
