The Arboretum in May

Lilac Sunday is over, but there are still some lilacs in bloom, so download the self-guided lilac tour [pdf] or the latest Tree-of-the-Month [pdf].

New! There are more than 15,000 plants in the Arboretum collection, and now they fit right in your pocket—in your smartphone, that is! We’ve launched two new mobile applications to help you find your way through the landscape and get information about plants around you. Help us test Mobile Collection Researcher (Mobile CR), and Arnold Arboretum Navigator.

Tree Mobs are the newest experiment in spontaneous learning at the Arboretum—on May 31, see what happens when you combine one expert, one amazing plant, and 15 minutes of your time.
