Salvia wagneriana - Wagner's Sage
Given enough water and sunlight Salvia wagneriana gets quite large, 10 feet or more. If it is kept on a rather spartan diet Salvia wagneriana should stay around 6 feet tall and wide. Wagner's Sage loves heat, it grows and blooms nonstop until the frost sets it back. Salvia wagneriana is damaged at 25° F or so but will recover from dips into the low 20°s. Salvia wagneriana is native to the mountains of Central America at an elevations of 4,000-6,500 feet. The climate there is warm and moist. Wagner's Sage will still bloom in light shade near the coast and in dry situations but really prefers the moisture, heat and light. Salvia wagneriana is a great addition to the hummingbird garden.
