Now, that's one very beautiful flower, thanks for sharing the photo :)

There's a few streets in my area lined with Bauhinia purpea. They look amazing for a month or so, especially in the wet years, but (like redbud) are rather nondescript otherwise. Still, a very well behaved street tree -- no sidewalk cracking, massive pollen loads, bug infestations or rampant invasiveness.
