MIMOSA NUTTALLII, SCHRANKIA UNCINATA also know as Sensitive Briar, Bashful Briar and Cat's Claw

Mimosa nuttallii, Schrankia uncinata, is also known as Sensitive Briar, Nuttall's Sensitive Briar, Nuttall's Sensitive-briar, and Bashful Briar due to its sensitive leaflets which fold when touched and and aptly named Devil's Shoestrings and Cat's claw because of its abundantly barbed stems.  the ball-shaped magenta-pink flower heads of Sensitive briar resemble miniature firework explosions and bloom on sprawling or trailing 4 feet long stems.  Sensitve Briar will grow best in dry to average soil and full sun on a bank , hanging over a wall, or naturalized in a prairie meadow.  It occurs naturally on glades, prairies, savannas, and roadsides.
