Road Trips Gardeners may have heard of the Barnes Foundation‘s art collection, but did you know that the Merion campus of the Barnes Arboretum, 300 North Latch’s Lane, Merion, Pennsylvania, continues the extensive arboretum and horticultural programs established more than 75 years ago by Laura Barnes, wife of Dr. Albert C. Barnes?

Open to the public on weekends, the arboretum features more than 2,500 varieties of trees and woody plants, many of them rare, along with other fragrant plants and flowers. There’s even a National Hosta Display Garden. Visitors are encouraged to bring a picnic and listen to the new 42-stop arboretum audio tour.
