Eastern Redbud

I usually don't have much to say about the Redbud except that it does well in NYC and is a reliable, shade-loving tree. But every spring when they start to bloom, they stop me in my tracks because of their unusual parasitic-like, clumping flowering habit. All the other flowering trees I know of bud out at the top of their canopy where the strongest light is. The Redbud branching becomes infected with flowers. These are located on Smith Street in Carrol Gardens.
