Mast Young Plants invites you to visit our trial garden during the 13th annual Michigan Garden Plant Tour. Representing over 25 breeders and showcasing nearly 100 genera and over 1000 varieties of plants, our trial garden offers you the opportunity to explore and experience a tremendous selection of new and exciting products.

Our trial garden is truly a living catalog, featuring varieties of ornamentals, herbs, vines, perennials, and grasses displayed in raised sun and shade beds, as well as 400 combinations in various containers and hanging baskets. All plants and combinations are clearly labeled for your convenience.


  • Expanded garden display. We are excited to offer additional garden display area this year, including labeled breeder trials from Ball FloraPlant and Green Fuse. To accommodate these exciting new trials, the AAS vegetable trials and taste testing have been discontinued. The AAS trial garden will continue to feature seeded and vegetative ornamental displays, including 15 seeded entries and 30 comparisons in row trials, as well as two vegetative entries and four comparisons in containers.

  • Blind comparison trials. Our fourth year of blind comparison trials will feature numerous breeder-designed combinations, including Dummen Confetti Garden and Garden Party, Selecta's Trixi, Ball's Mix Masters, Danziger's Mixis, Syngenta's Kwik Kombos, Westflower's Passion Combos, as well as several new offerings from Suntory.

  • Knowledgeable and helpful staff. We are eager to welcome you to our trial garden and will be happy to assist you. Appointments are not necessary, but we are happy to provide you with a guided tour upon request.

  • Shaded sitting and meeting space with wireless internet.
