Salvia clevelandii, 'Winnifred Gilman' is an evergreen shrub with flowers lavender to blue. This form of Cleveland sage that is native to dry slopes San Diego County (we would guess it has a little  Salvia munzii in it, but as it came from Strybing Arboretum it could have a little of something else, or the form found in the wild had a little munzii in it.). It likes sun and perfect drainage. The gray-green leaves have intense fragrance. All the Salvias are great hummingbird plants. Cold tolerant to about 10 deg. f.. It has managed to survive lower temperatures here but I had it against a 3' rock wall facing south situated in such a way that the cold flowed over it. 'Winnifred Gilman' flowers are stunning. The interesting note is, at least here, the only native pollinators seem to be young  hummingbirds.
