It was on Sunday, June 9th and I believe it was after a big rain, but the New York Botanical Garden (in the Bronx) was as green as I've ever seen it. Most of the tree blossoms (cherry blossoms, magnolias) had come and gone and the Azaleas were nowhere to be seen (they may not have blossomed yet), so there wasn't much in the way of actual flowers, but the tree leaves, bushes and grass were vibrant in their greenness.
This is the path I usually take after entering the Garden and heading north.
