About Us

For six generations, the Yerke family has been growing in Wisconsin. The family business began in the mid-1800's with Great-Great Grandpa Albert's dairy farm and field crops. His son Henry later raised vegetables, herbs and flowers for Wisconsin farm markets.

When fourth generation Harold built the first greenhouse in 1954 people from all over Southeastern Wisconsin discovered Yerke Greenhouses and traveled to the Mukwonago Frog Alley Farm for flowers each Spring.

We celebrated the greenhouse's 50th Anniversary in 2004.

Fifth generation Gilbert and wife Gail and family expanded the greenhouse operation in 1987, opening a new Garden Center near the village of Mukwonago. Almost 20 years later they again focused on relocating back to where it all began at the family's historic Centennial Farm on Frog Alley Road.

Yerke Frog Alley Greenhouses "The Flower Farm" reopened in Spring 2006, continuing to offer the best regional selection of bedding plants, perennial flowers and floral hanging gardens. The youngest of four children, son Christopher joined the business in 2004 and has stepped up to help operate the Frog Alley location along with Gilbert.

Growing over 1500 varieties of Annual and Perennial flowers, they offer unique floral hanging garden designs along with annual and perennial flower varieties each spring.

A member of Mukwonago's "Flower District", you'll find unique new floral varieties as well as heirloom plants at Yerke's Frog Alley Flower Farm. The Yerke family also offers certified organic vegetable plants and herbs.

The farm is open to the public mid-April through late summer.

"From generation to generation, Wisconsin families have come to expect quality, unique plant varieties and old-fashioned friendly service here at Yerke Greenhouses. We truly do appreciate your business and friendship and welcome you to stop out at our family farm this spring!"
