Salvia leucophylla 'Point Sal'

Salvia Point Sal is a gray ground cover that generally grows 3-4 foot across and a few inches tall. BUT, there seems to be more than one flavor in the trade. It is supposed to be less than one foot tall but in one location it grew to 6 ft. tall and 12 ft. wide. (Customer was NOT amused!) Allen Chickering has the same problem, three or four flavors. We seemed to have found a form that is correct and stays low. It is a good groundcover plant for coastal bluffs. But in a garden in Escondido, in part shade, it was a low attractive mound of gray, about two foot tall and four foot wide.
