Mexican Bush Sage, Salvia leucantha, is a xeriscapic, evergreen, perennial, sub shrub plant. This means that the Mexican Bush Sage is perfect for landscape designs that are in areas that have high temperatures and low rain amounts, the leaves and shrubs do not die off, it lives for more than 2 years and it is a low growing woody shrub. Mexican Bush Sage grows best in the USDA Hardiness Zones 7 through 11.
Blooms and Leaves:
Mexican Bush Sage has flower spikes with blooms that are velvety to touch and range in color from lavender-blue to purple. These sub shrubs bloom from late in summer to the first frost in fall. Removing the dead blooms will encourage the plant to produce more.
The leaves of the Mexican Bush Sage are a gray/green color and are wooly and white underneath. This shrub will grow up to 3 feet tall and 3 feet wide with branches that arch and are graceful looking.
Caring for a Mexican Bush Sage includes knowing where to put it in your landscape design. These small shrubs do best in an area that gets full sunlight, but a little afternoon shade will not hurt it, especially in areas that get extremely hot. The soil that this plant prefers is one that is sandy and rich but has really good drainage. Overall, this plant is very low-maintenance, especially after it is established in the landscape.
Propagation is done by taking root division and stem cuttings. Root division can be done by cutting the root between the parent plant and the offspring and then planting the young plant in a pot until it is growing well. Stem cuttings can be put in water and allowed to root then placed in the landscape. Either way is fairly easy and should provide a new plant or plants.
Mexican Bush Sage has many uses in a landscape. It can be used as a mass bedding plant by using several in an area, in a container on a patio, in a perennial border garden or it can simply be a landscape specimen and used by itself. Mexican Bush Sage can also be used as a cutflower where it will last several days. Hummingbirds and butterflies are attracted to Mexican Bush Sage as well.
