Celestial Blue has lovely royal blue flowers and purple bracts. Sun-loving, heat tolerant and drought resistant, it was discovered at Las Pilitas Native Plant Nursery in Southern California.
This fragrant sage blooms and blooms throughout the heat of summer. Tolerant of everything but wet feet during summer, it withstands winter temperatures as low as 10 degrees F for a short time as well as lows in the 20-degree range for days.
Use this pretty plant in tough soils, on banks and in areas where watering is difficult or undesirable. Butterflies, honeybees and hummingbirds love it, but deer leave it alone. This cultivar is one of the best Salvias for cut-flower arrangements.
