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. | Bog Sage or Blue Spike 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. | 6 - 10 |
Size (h/w/fh) The anticipated mature size of the plant: Height, Width & Flower Height. | 40"/40"/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 |

This fragrant sage's common and scientific names don't communicate its beauty or growing range. Both names refer to the boggy conditions in which it grows in the wild in Argentina, Brazil and Uruguay. However, although it appreciates moisture, Bog Sage also does well in dry conditions that cause this stoloniferous plant to spread less.
Lovely sky-blue blooms, with white beelines on the upper and lower lips, top the many slender, graceful stems from summer to fall. When swaying in the breeze at the back of a perennial border or as part of a screen, Bog Sage is a pleasing sight for butterflies, honeybees, hummingbirds and humans alike.
Although it has an average height and spread of about 40 inches with flower spikes making it a bit taller, Bog Sage sometimes can reach heights of more than 72 inches, according to Mississippi State University.
Partial shade is preferable, but Bog Sage also grows well in full sun in all but the hottest and most arid environments. Cold and heat tolerant, it grows well in regions ranging from the arid Rocky Mountain West to the humid Deep South. Give it partial shade if possible. Full sun is fine in all but the hottest and most arid environments. We always sell out of this plant early in the season.
