    Utah Native Plants for the Landscape: Creeping Barberry

     
    Mahonia repens

    Creeping barberry (Berberis repens) is a small, woody groundcover that is native to most of western North America.  It is typically 6-24 inches tall and is characterized by evergreen compound leaves that are dull green in the summer and changing to various shades of red to purple in the winter (Fig. 1).  barberry has a bright, yellow flower that develops in racemes from the leaf axil (Fig. 2).The flowers give rise to dusky, dark blue berries about 1/3 of an inch in diameter (Fig. 3).  It grows most actively in the spring, but can grow at different times of year depending on conditions.

     

    Mahonia repens in flowerCreeping barberry can propagate itself by seed, rhizomes, stolons, and stem layering (Fig. 4).  As a result, this plant can spread in the landscape, though not aggressively. One of the advantages of creeping barberry is that it is tolerant of full sun, partial shade, and heavy shade.  As a result it is a good option for dry, shady areas that are difficult for many plants.  Once established it requires minimal maintenance; primarily limited to trimming it back and cleaning up debris and litter than can get trapped in the leaves and stems.  It is also resistant to deer and attracts pollinators when in bloom.

    Mahonia repens berryCreeping barberry prefers well-drained neutral soils, but can thrive in shallow, rocky soils.  Size and vigor varies with habitat, with poor conditions producing small plants with only one shoot and one or two leaves, while favorable conditions produce more robust plants or mats of plants.  But, regardless of size, creeping barberry persists widely.
