(Giant Purple Desert Sage) It’s best to plant this flamboyant native of the Southwest in spring or summer. However, once established, it tolerates winters from USDA Zones 5 to 9. Purple tubular flowers and burgundy bracts flare up its 10-inch flower spikes like flames on this softly rounded shrub.
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. | Giant Purple Desert 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. | 5 - 9 |
Size (h/w/fh) The anticipated mature size of the plant: Height, Width & Flower Height. | 24"/24"/36" |
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. | Drought resistant |
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. | 2 to 3 feet |
Mature spread The mature width of this plant in average conditions. | 2 to 3 feet |

Fragrant, drought resistant and heat tolerant, this is a sage that isn't particular about soils as long as they drain well. Give this shrub lots of sunshine and little water for best performance. We have learned by experience that this species grows best where there are definite seasons, and where the winters are not particularly wet. They thrive in Denver, and languish in Los Angeles.
Blue Flame's improbably lush flowers are offset by distinctive silvery foliage. It does well in dry, gravelly gardens as a groundcover, border or pathway edging and is just right for a native garden focusing on the Southwest or a wide variety of American native species.
Expect Blue Flame to grow up to 36 inches tall and 24 inches wide and to flower from summer to fall. Expect to fall in love with it; certainly butterflies, honeybees and hummingbirds do. Luckily, deer avoid it.

This native of the dry Western US can be very difficult to grow outside of natural growing areas.
