their plant list online. The buds remind me a lot of the Swamp Azalea (Rhododendron viscosum) in the bed right outside of Native Flora at Brooklyn Botanic and I wouldn't be surprised if it is that species. (It is on the plant list)
And the bright orange leaves on a cutleaf Sumac. A garden is never just about the flowers, and in the fall and in a place like The High Line, that's incredibly easy to see. It's almost time to start focusing on buds again and the beauty beyond the blooms, a good project to take me through a cold winter.
