About this Outdoor Garden

Explore an abundance of cultivars in this new Garden that showcases our research and plant evaluation processes.

Changing annually, the Trial Garden puts new cultivars to the test against tried-and-true favorites. Data on these mostly tender perennial and annual species is evaluated and recorded biweekly throughout the summer, and only top performing plants will be approved for use in future displays.

Which Plant is Your Favorite?

Your opinion is of great value to Longwood and the horticulture community including gardeners, nurserymen, and plant breeders. Knowing which plants the public prefers allows our designers to create remarkable displays and helps the industry focus their efforts. When you visit the Trial Garden, be sure to stop by our voting station and cast your ballot for your favorite plants. We’ll tally the results and publish them here.

Garden Highlights

History of this Garden

This Garden was formerly dedicated to groundcovers, ornamental grasses, vines, and roses. The ornamental grasses have remained in the Garden, but have been relocated to the easternmost bed where they are displayed in long, naturalized sweeps. The new Trial Garden is located within the greater Idea Garden.
