2018 RRTG HIGHLIGHTS:

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

New this year, expanded focus on Perennials. Raker-Roberta’s is your place for Perennials. In our Gardens this year, we will be showing 1st year flowering plants. We will also show off our breeding partner’s latest and greatest offerings. These will be in our main gardens.

We are comparing Begonia Big vs. Whopper vs. Dragon Wing vs. Megawatt, by series and also by color.

We are also comparing SunPatiens vs. Sun Harmony vs. Sun Standing Impatiens

Other items in our Comparison sun row area are: African Marigolds, Zinnia, Lantana, Gerbera, Argyranthemum, Verbena.

Last year was the first year we experienced Impatiens Downy Mildew. As a result we will once again be showing shade alternatives to Impatiens walleriana. We will also be showing Lobelia in large containers in the shade.

In our Hanging Basket comparison area we will be showing Lantana, Vegetative Petunias, Ipomoea and Euphorbia.

We also are an AAS trial and display garden site. This year our display gardens will include decorative containers.

We will also have Basil in a dedicated landscaped bed along with a "Farm-to-Table" bed, showcasing AAS vegetable winners.

We are a founding member of the Michigan Garden Plant Tour! This year, the tour is from July 30th through August 10th, Monday - Friday. Join us, Michigan State University, Four Star Greenhouse, Mast Young Plants and Walters Gardens to see the latest and greatest varieties on the market!
