Sensitive Briar

Ah, here is the lovely pink blossoms i've been wondering what their origin is.

Warren, Last month I took about a dozen pictures of these wonderful little blossoms at the Hypoluxo Scrub Preserve and hadn't got around to trying to identify them. We used to grow Sensitive plant as a houseplant several years ago and I didn't realize that they ever blossomed! I have learned a lot today from your photo!! Thanks!! :-)
