About Us

     For six generations, the Yerke family has been growing in Wisconsin. The family agribusiness 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 Grandpa 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. The Greenhouse business celebrates its 63rd Anniversary this Spring.

      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 then 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 family business from 2004 thru early 2011, operating the Wales Hwy 18 Spring Greenhouse and Frog Alley location along with Gilbert.
Today you'll find daughter Nateal managing the farm retail business and helping Dad, Gilbert, with the growing operation as well. 

Growing over 1000 varieties of Annual and Perennial flowers, the family farm offers unique Artisan Floral Hanging Garden Designs along with annual and perennial flower varieties each spring. You won't find a better selection of vegetable and herb plants anywhere else with over 100 varieties of vegetable plants alone.
The Yerke family also offers USDA CERTIFIED ORGANIC vegetable plants and herbs.
You will discover unique new floral varieties as well as heirloom plants at Yerke's Frog Alley Flower Farm. The Frog Alley farm is open to the public from late April to late July.

Pictured above , left, are Gilbert's grandparents Minnie and Henry Yerke.  Above right are his granddaughters Sky and Aurora.  The Yerke family was later blessed with two grandsons, Leo & Spencer, and granddaughter Magnolia Rae. (yup, guess they're bragging a bit here) 


"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!"
