The blue flowers of the common and loved herb rosemary rivals that of Ceanothus and Lithodora. That is on certain varieties.

The obvious Salvia flowers on ‘Mozart’ are thick on the stems and are entirely dark blue- no interior dots of white or white splotches. Full sun and water to establish in average soil. Extremely drought adapted when established. This strongly arching shrub goes up to about 30″ and spreads to 4′ wide. Hillsides, the top of rock walls, containers subjected to reflected heat. Pork roast. Very good culinary use/taste for this plant. Hardy to about 5ºF. Good drainage improves cold hardiness. Tolerates the hottest places with no stress. Aromatic waxy resin will attach to your fingers. Blooms on wood from the previous season. Prune or harvest when needed after blooming has ended. Some deer resistance. Extraordinarily drought adapted. Great performance at the Oregon coast.
