Tree Mobs have gone virtual! Join the Arnold Arboretum online for interactions with scientists or other specialists at the Arboretum via Zoom, and enjoy diverse perspectives on our plants and landscape. Visit http:/arboretum.harvard.edu and create a profile to receive Tree Mob notifications, and look for a new program nearly every week. Also view past Mobs in their entirety on our YouTube Channel, like a discussion of colorful spruce cones with Director William (Ned) Friedman, seen at https://www.youtube.com/watch?v=ujqW9j-aT60
