Description:
A great shade plant, named because it can also be found growing in the dense shade of Ashe junipers (mountain cedars). It also grows under oaks and mountain laurels. A small plant and well behaved, with little furry round or heart-shaped leaves with scalloped margins. Makes a wonderful ground cover with brilliant red-spiked flowers lasting 4-6 weeks. Flowers are 1- to 2-inch spikes from March to August. Usually grows 1 to 2 feet tall. Native to the Edwards Plateau, Trans-Pecos Mexico.

Deer Resistance:
Observed heavily eaten under pressure.

Planting Sites:
Plant on well-drained sites in shade, part shade, or dappled shade. Soil may be sand, loam, clay, limestone.

Planting Instructions:
Dig hole at least 2 times wider, but the same depth as the root ball in the nursery container. Carefully remove plant from container, taking care not to break the root ball. Loosen exterior roots, if root bound. Plant at a depth equal to thickness of the soil in the container. Do not add any soil to the top of the root ball. Adding a layer of 3-4 inches of mulch after planting is desirable. Space plants 1 foot apart.

Watering Instructions:
Water in well after planting, using root stimulator according to directions. Water deeply every 7-10 days, checking an inch or two into soil at edge of root ball to determine soil moisture. Skip a watering after a rainfall of ½ to 1.

First fall/winter:
Maintain this watering schedule until the first fall after planting. Reduce water during fall and winter. In a “normal” year, no watering may be necessary in fall and winter, but during a dry period, monthly watering may be desirable.

Second spring and thereafter:
Water monthly only in periods of drought. Once established, cedar sage will survive with little supplemental irrigation.

Other care:
To maintain as a thick ground cover, allow seeds to ripen and scatter, and then water it periodically.

NICE! Tip:
Plant cedar sage in place of periwinkle (Vinca major).

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
