We've got to get back to the Gardens!


In addition to our extensive sponsored areas (Landscaped beds, rows, large containers and Hanging Baskets) we have exciting things planned for our Comparison areas. 

  • Unfortunately, due to COVID-19 we are forced to make some changes; We are cancelling The Connection this year. We also will not be hosting lunches or giving greenhouse tours.
  • The Michigan Garden Plant Tour will be Monday through Friday from July 27th through August 7th.
  • Our sponsored areas are full with the latest and greatest offerings from our breeder sponsors.
  • This year in our comparison row trials in the sun, we will have Lantana, Vinca, Angelonia, Pentas, Salvia, French Marigolds and Rosemary. 
  • In the Shade, we'll have Diascia and Torenia.
  • We'll also be showcasing cut flowers, container vegetables, and the new "speckled" Petunias.
  • In our hanging baskets, we are showcasing the Lantana, Vinca and Begonia boliviensis.
We are adding to our extensive perennial trials with Lavender, Agastache, Digitalis, and Gaura. These are in addition to our existing perennial trials.

This year, we will be adding videos and much more photography to this site as well as our social media accounts. Stay tuned!
