(Rock Purslane)  This succulent, gray leaf perennial is a stunning addition to the dry Salvia garden.  Pair this with yellow flowered Salvia x jamensis varieties and stand back.

The 2 inch fluorescent purple flowers resemble poppies, with papery petals and prominent stamens.  They are displayed on toll, branched flower spikes all season long.  The leaves are in tight rosettes, attractive in their own right.

A drought resistant plant that can tolerate dry periods, Rock Purslane does appreciate regular watering.  A lovely addition to any mild climate garden.
