Serving gardeners since 1897

We’re employee owners, horticulturalists and hard working gardeners, but we also think of ourselves as plant farmers. Our healthy and thriving nursery stock is grown by us with great care to make sure you receive the best plants possible. Whether you're a homeowner shopping for a shade tree, a gardener with over 20 years of experience, a beginner trying to create a wildflower garden, or a millennial trying to learn more about edible gardening, we have something for you! Shop our mail-order plants now!


Sustainability and earth-friendly practices are not new to us. Since 1897, we have been caring stewards of our growing fields, which now numbers over 1,500 acres. Community is important to us and being good neighbors to the many family farms that make southern Wisconsin famous. 

As one of the largest and oldest nurseries in Wisconsin it has been our mission to produce and care for our nursery stock in the most eco-friendly way possible. We're a company of employee owners, which means we're not about a bottom line. We're a company of team players that want the best for you and the plants you're purchasing. Even though we're one of Wiscosnin's largest nurseries, you would never know by our attentive and knowledgeable staff. Our team is packed with horticulturists, landscape designers, gardeners, plant specialists, botanist, and everything between. We care about you and want to see you have a positive experience with our plants, it's that easy.


Shop plants in-person - Madison, WI

In January of 2016 McKay became the owner and operator of McKay Garden Center - Oregon (formerly known as Winterland Nursery) south of Madison in Oregon, WI (click here for hours, location and more). If you want to see plants in person and buy them on the spot this is the place to go. You cannot view and shop our plants in-person at our Waterloo, WI location (750 S Monroe St.) Our garden center has 15 acres worth of nursery stock to choose from...

  • Perennials
  • Shrubs
  • Unique evergreens
  • Large shade and ornamental trees
  • Native plants and edibles
  • Decorative planters & gardening accessories
  • Seasonal items like hanging baskets and annuals

Since our Waterloo, WI location (McKay Nursery Company) is a working nursery, for safety reasons, we do not allow visitors to select plants from our nursery fields. Please visit our Madison garden center instead to view and purchase plants in-person. We promise you won't be disappointed.

Our Eco-Friendly Buildings - Waterloo, WI

Beyond energy-saving construction, insulation, and management of our production and storage facilities, we significantly reduce our energy consumption by collecting expended lubricating oil from our many machines and using it as heating fuel. But we do not stop there. Using a device designed and built by one of our owner-employees, we compress the steel oil filters, purging even more of the oil for recycling, which then allows us to recycle the filters themselves as scrap steel. This puts to economic use what would otherwise be a pollutant, which is good for the land, good for our 150+ owner-employees, and ultimately good for you as our customer. 

Our state-of-the-art office system gently diverts the roof water into “rain gardens.” These are planted with flowers and other greenery that absorb rainwater rather than have it run off to pollute and scour the landscape. It also increases the amount of water that filters into the ground, recharging the local aquifer; protects our neighbors from flooding and drainage problems; protects nearby streams and lakes from stray pollutants; and provides valuable habitat for birds, butterflies, and many beneficial insects.
