Mealy blue sage

**ARCHIVED POST **

Low-maintenance and long-blooming perennial

Mealy Blue Sage, Salvia farinacea, also known as Mealycup Sage, is an herbaceous perennial. It is native to New Mexico and Texas; its native habitat includes prairies and the edges of woodlands. Its names “Mealy” and “farinacea” both refer to the way the sepals (the parts around the flower petals) look, which is as if they were dusted with flour or meal and is caused by tiny hairs on them. Mealy Blue Sage grows 18-36 inches tall and 18-36 inches wide. Its leaves are usually about 3 inches long, greygreen to green, and lanceshaped.

Flowers and Seeds: Mealy Blue Sage blooms from April until frost with a bloom peak in April and another in late September or October. Flower spikes with many florets are held above the foliage. The flowers range from white to violet-blue and are 2/3–3/4 inch long, with two stamens and a pistil. Seeds may be collected following flowering.

Planting sites: Mealy Blue Sage thrives in full sun and partial shade, although it blooms more profusely with more sun. It tolerates a range of soil pH.

Watering Instructions: Like many Texas natives, Mealy Blue Sage may need supplemental water during its first season in the garden, but after it is established, it will only need water in an extended drought. Too much water will result in it being “leggy”. Mealy Blue Sage should be planted where it will receive adequate drainage; it will not tolerate “wet feet.”

Comments: Mealy Blue Sage is a great plant for North Texas. It has a nice fragrance, is deer resistant, blooms for a long time and is drought resistant. It attracts butterflies and hummingbirds and has been recognized by ecologists for its value of attracting native bees. Several named cultivars are available in nurseries including both “Henry Duelberg” and “Augusta Duelberg”. These selections were found by Greg Grant in a nonirrigated section of a rural Central Texas cemetery in midsummer around the graves of the Duelbergs. “Henry Duelberg” is deep blue, while “Augusta” is white.

All Mealy Blue Sage varieties may be pruned to about half their height in midsummer to encourage more compact growth in the fall. In addition to propagating it through seed, Mealy Blue Sage may also be propagated via cuttings.

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 fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
