Annual Comparison Trials

2019 Dahlia Trial

Each year the National Garden Bureau selects one annual, one perennial, one bulb crop and one edible as their “Year of the” crops. Plants are chosen because they are popular, easy-to-grow, widely adaptable, genetically diverse, and versatile. In 2019, they selected the Dahlia!

So this year, we gathered more than 200 Dahlia varieties from the world’s finest breeders and grew them in our 2019 Annual Comparison Trials!

All-America Selections Trial Ground

We have been an All-America Selections (AAS) trial site since 2012.

 The Michigan Garden Plant Tour

The Mast Young Plants Trial Garden is also a destination on the Michigan Garden Plant Tour! This is a free, coordinated open house of leading young plant producers of ornamentals and Michigan State University. The objective of the tour is to educate growers and industry professionals about new and existing garden plants and how they perform in different settings.

Greenhouse growers, landscapers, garden center operators, and nurserymen are invited to participating tour sites during the two week period.

The Michigan Garden Plant Tour takes place during the last week of July and the first week of August each year.

Expect to learn about a wide range of ornamental crops, including popular commercial brands of annuals and perennials. This is a terrific way to observe plant performance at different locations and grown under various conditions, both in the ground and in containers.
