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 and this year’s tour is scheduled for July 24-August 4, 2023.

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