sensitive plant, Mimosa pudica

Please be careful and courteous around sensitive plant. It is really sensitive. If you touch it, it will fold its leaves in retreat. That feature has long fascinated us. But did you know that it also remembers you? Touch it repeatedly, and it stops hiding. It remembers that you're not going to hurt it, and remains open. Shy and sensitive, but it can get over it. Sensitive plant has spread from cultivation in FL, HI, MD, and VA. Beal Gardens MSU, 6/24/12. Bean family, Fabaceae.
