Description:

Agarita, Mahonia trifoliolata, is an evergreen, holly-like, native Texas shrub that grows 3-6 ft. tall 3-5 ft. wide. It has stiff, spreading branches holding gray-green to blue-gray sharp-pointed, thorny leaves. Agarita leaves are 2-4 inches long, separated into three narrow leaflets further divided into lobes that are tipped with sharp spines. In nature, Agarita is found on hillsides and wooded areas and can form thickets.

Flowers and Seeds:

Agarita blooms in February to March each year with cheery, fragrant, yellow, half-inch flowers with six petals and sepals. These are followed by small green berries that ripen to bright red from May and feed the birds until June. The berries are edible.

Planting sites:

Agarita thrives in full sun to part shade. Full sun yields plants with the highest numbers of blooms and berries. The color of the foliage is also affected by sun exposure, with shadier conditions producing greener leaves and sunnier situations making grayer leaves. It is tolerant of most soil types as long as they are well-drained.

Watering Instructions:

Water Agarita when planting it or its seed. Once established, it is drought tolerant.

Comments:

Agarita looks great all year in several types of locations, as a stand-alone shrub or as a hedge. With its sharp leaves, it’s good as a barrier plant or security hedge. It is a wonderful substitute for non-native holly bushes, like Dwarf Burford Holly (Ilex cornuta). When working around Agarita, protective gloves are recommended to protect hands from the spines on the leaves. Dead fallen leaves on the ground are even sharper. Agarita’s mid- to late-winter blooms are a harbinger of spring and the edible berries that follow make a great-tasting jelly. However, those berries are hard to pick because of the sharp, scratching leaves. One tip for gathering the berries is to maneuver an open umbrella under an Agarita loaded with fruit and shake the bush until the berries fall into the umbrella.

Agarita berries are a favorite food for birds. Ground birds, like quail, and small animals use the plant for cover. Agarita is deer-resistant, probably because of the prickly leaves. Additionally, Agarita is tough, it survived the February 2021 winter freeze.

Thank you for using native plants in your landscapes. Look for the NICE Plant of the Season signs and information sheets on your next visit to a participating North Texas nursery. 

 

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.
