A frequently seen native locust in the South is the honey locust. Compound leaves and distinctive flowers: heavy, almost drupelike white flower clusters in late spring. I saw extraordinarily beatiful honey locusts this weekend outside of the Hyatt Regency in Reston, Virginia--very mature specimens with the distinctive bark of the mature locust: elephant-skin-textured with occasional cracks in it like the cracks you sometimes see in dried field clay.

There is also a native locust called the black locust, but I'm not on speaking terms with that one.
