Salvia mohavensis

(syn. Audibertia capitata, Audibertiella c., Ramona c.) Mojave sage is a nice little perennial sage from the Little San Bernardino mountains to the Clark mountains of Nevada. Bright fuzzy green leaves with cool blue flowers make this plant very different. In grows in hell, well not quite. It's actually in the mountains west and south of Las Vegas that are beautiful in winter and spring. The washes where this sage grows has a delightful mix of Desert willow, Catclaw, a form of Squawbush and Rabbitbrush. But then summer shows up. This is not a plant for fools. It should do well in a desert garden or a rock garden with excellent drainage. It is not super drought tolerant and likes a little water now and again. Wash the foliage off maybe once a week during summer, without really getting the ground wet and you'll be close to what it wants. It can easily be overwatered by rainfall in northern California.
