(Purple Stem Sage) Deep purple stems and cobalt blue flowers with pronounced white beelines and dusky gray calyxes cause this sage to command attention.
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. | Purple Stem 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"+/36"+/60"+ |
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 |
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 |

Aside from knowing that Purple Stem Sage was collected in the Northern Mexican state of Tamaulipas, little can be said with certainty about the taxonomy of this mystery hybrid Salvia. What we can say definitively is that it is easy to grow, flowers abundantly and does well in heat with limited water.
Purple Stem Sage is a waist-high, upright subshrub that combines tender herbaceous stems with woody growth. It looks particularly pretty planted in front of silvery leafed sages.
This drought-resistant sage does well in full sun to partial shade. It needs soil with good drainage and fits in nicely with California native sages.
Highly recommended.
