We've got to get back to the Gardens!


Stay tuned for this year's results and next year's entries.

We will be hosting our big annual summer event, The Connection!

Join us on July 29th for a day filled with Music, Food, Friends and of course, Flowers! Industry experts will be on hand to talk about the latest and greatest offerings. Be sure to make time to visit.

We will not be offering daily lunches or giving greenhouse tours.

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

  • The Michigan Garden Plant Tour will be Monday through Friday from July 26th through August 6th.
  • 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 Sunflower, Basil, Gazania, Osteospermum, Coleus (sun), Seed Petunias, Lisianthus, and Lobelia.
  • In the Shade, we'll have Fuchsia and Lobelia.
  • We'll also be showing Thunbergia in large containers.
  • In our hanging baskets, we are also showcasing Calibrachoa.
We are adding to our extensive perennial trials with Lupine, Hardy Hibiscus, Monarda, and Nepeta. These are in addition to our existing perennial trials.

Last year, we added videos and much more photography to our social media accounts. Search for "Raker-Roberta's" on to see all of our videos. We'll continue to provide the best multi-media content available.


2021 is the National Garden Bureau's Year Of The Sunflower, Monarda, and Hardy Hibiscus!

Nepeta is also the Perennial Plant Association's 2021 Perennial of the Year.

Be sure to pick your favorites.
