Are you seeking a hardy, low-maintenance, and long-blooming native North Texas plant for your landscape? The Mealy Blue Sage (Salvia farinacea) provides a winning combination for the North Texas native plant enthusiast. In recognition of its beauty and low maintenance requirements, the Lady Bird Johnson Wildflower Center honored the plant as its winner of the 2023 Wildflower of the Year.

Easy to Grow and Love

Mealy Blue Sage is a perennial native to large parts of Texas, along with small sections of Oklahoma and New Mexico.  This resilient plant is commonly found in many regions of our state, due to its ability to thrive in prairies, meadows, and open woodlands.The common name derives from the vibrant blue flowers, and “mealy” refers to the white, powdery substance that coats the plant’s stems and calyxes.

Drought–tolerant and deer–resistant, Mealy Blue Sage typically reaches 2 – 3 feet in height and usually forms a mound as wide as the plant is tall. It can be used in perennial borders, native beds, and naturalized areas.

What sets Mealy Blue Sage apart is not just its captivating appearance but also its multifaceted benefits:

Six Reasons to Love Mealy Blue Sage

  1. With an exceptionally long bloom period, Salvia farinacea can add color to your gardens from early spring to late fall. Its vibrant violet-blue flowers create a delightful visual display. Its flowering period can be enhanced further by pruning to produce thicker, more compact foliage, and increased flower production.
  2. This resilient charmer is an excellent addition to almost all North Texas landscapes. As a Texas native, it can withstand our brutal summers. It thrives in full sun to partial shade and is tolerant of various soil types, including sandy, loamy, and clay soils. Once the plant is established, it thrives with minimal supplemental water.
  3. A prolific pollinator, it enhances any North Texas pollinator garden. With its nectar, it helps support a host of bees, hummingbirds, and butterflies.
  4. As a native plant species, Salvia farinacea plays a crucial role in helping support biodiversity. In addition to its nectar production, its seeds provide sustenance for various bird species and small animals.
  5. With its combination of toughness and beauty, Mealy Blue Sage should be an easy choice for North Texas gardeners. The plant’s slender, upright stems form dense clumps adorned with lance-shaped leaves. Plus, the distinctive blue flowers on elongated spikes are contrasted by the plant’s silvery-green foliage.
  6. Mealy Blue Sage is adaptable to a wide range of growing conditions. While not particular about its location, planting in well-drained soil is vital to promoting growth and flowering. Additionally, it does best with a minimum of 6 – 8 hours of sunlight daily. Like most sun-loving natives, less sunshine typically results in more sprawling and taller plants.

Whether you are an experienced gardener or just beginning, Mealy Blue Sage should be on your spring native plant shopping list. This winner of a plant can bring a fantastic combination of beauty and resilience to your garden.

A reminder that the Heard Museum and Wildlife Sanctuary’s spring native plant sale will be held on April 12 – 14, 2024. Note that April 12 is for Heard members only.

About the Region

New Braunfels, the location of our Fall 2024 Symposium, straddles both the Edwards Plateau Ecoregion and the Blackland Prairie ecoregion. Interstate 35 divides the city of New Braunfels; its path through the city closely parallels the boundary of these two ecoregions, with the Edwards Plateau on the west side and the Blackland Prairies region to the east. 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.
