Roger Williams Botanical Center
My husband and I recently went to the Roger Williams Botanical Center in Providence to get a dose of green plants to counteract the dreariness and snow outside in a New England winter, and it was amazing!

Here are some of my favorite photos from that excursion.
I can also recommend the Lyman Estate greenhouses in Waltham! Smaller but chock full of interesting plants.
