Kudos to A.F. Donna for spotting this at Wilson Mountain. There is an area just full of these low shrubs all hung with pink blossoms. Pea family. Native to the southeastern U.S…. so these have somehow escaped and migrated northward.
Bristly Locust (Robinia hispida)
Once again, thanks for giving me a name for a plant that I noticed but could not identify (not to mention the great view … who knew prickly).
