(Black Stem Mountain Sage) Intense cardinal red flowers, stiff black stems and large, ribbed, green leaves make this Salvia microphylla stand out. Its color and upright growth make it dramatic amid a group of soft, rounded Salvias.
Common name This is the non-scientific name used for a plant. A plant may have several common names, depending on the gardener's location. To further confuse the matter, a common name may be shared by several completely different plants. At Flowers by the Sea, we rely on the scientific name to identify our plants and avoid confusion. | Black Stem Mountain Sage |
USDA Zones The U.S. Department of Agriculture plant hardiness zones indicate the temperature zones where a plant is likely to thrive. It is determined by the average annual winter minimum temperature. Actual winter temperatures may be higher or lower than the average. | 8 - 9 |
Size (h/w/fh) The anticipated mature size of the plant: Height, Width & Flower Height. | 48"/24"/48" |
Exposure This is the average amount of sunlight that a plant needs to thrive. Generally, full sun exposure is 6 or more hours of direct sun daily while partial shade is less than 4 hours of sun or dappled shade all day. Plants may tolerate more sunlight in cooler climates and need afternoon shade in extremely hot climates. | Full sun to partial shade |
Soil type This is the kind of soil that a plant needs to thrive. Most plants require a well-drained soil that allows the water to soak into the soil without becoming soggy. Sandy and clay soils can be improved by digging in compost to improve drainage. | Well drained |
Water needs Plants have specific water requirements. Water loving means the plant needs regular watering to keep the soil moist. Average generally indicates applying 1 inch of water per week, or watering when the soil is dry to a depth of 3 to 4 inches. One inch of water is equal to 5 gallons per square yard of soil surface. | Average |
Container plant? "Yes" indicates that this plant can be successfully grown as a container plant. | Yes |
Hummingbird plant? Hummingbirds have been observed regularly feeding from this plant's flowers. | Yes |
Mature height The mature height of this plant in average conditions. | 3 to 4 feet |
Mature spread The mature width of this plant in average conditions. | 3 to 4 feet |

Mountain Sage usually ranges from 24 to 48 inches tall. This is one of the larger varieties. The species is native to the American Southwest, most parts of Mexico and sometimes is found further south in Guatemala and Belize.
Mountain sages grow well in full sun and partial shade. This one does very well in partial shade and even blooms in full shade. Due to originating in the warmer climes of Belize, it is less cold hardy than many cultivars of the species.
In USDA Zones 8 to 9, Black Stem blooms from spring to fall, but with little production in summer. Except for good drainage, it isn't picky about its soil. Depending on local conditions, it may fit into either a perennial or shrub border. Black Stem also looks pretty as a background planting or screen. Heat and drought tolerant, it does well in dry and native gardens. We highly recommend it, and so do hummingbirds.
