Texas Barberry

Mahonia swaseyi

Texas Barberry is an evergreen central Texas shrub with yellow winter flowers and blue berries. It prefers well drained, often limestone soils and part shade.

Key Facts

  • Evergreen, multi-stemmed shrub with pinnate leathery leaves
  • Native to central Texas and associated limestone outcrops
  • Showy yellow flower clusters appear in late winter to early spring
  • Produces blue to blue-black berries that attract birds
  • Prefers well drained soils and can tolerate dry, calcareous sites
  • Performs in part shade to full sun depending on heat and moisture
  • Used in native plantings, erosion control, and low water gardens

Texas Barberry is an evergreen, multi stemmed shrub native to central Texas. It has pinnate leathery leaves, showy yellow flower clusters in late winter to early spring, and blue to blue black berries used by birds. It fits dry, well drained sites such as limestone slopes and low water gardens.

Identification

Mahonia swaseyi is a low to medium shrub usually three to six feet tall and wide with pinnate leathery leaves. Late winter to early spring brings upright clusters of yellow flowers that age to blue or blue black berries. The plant forms multiple stems and may produce basal shoots that expand clumps over time.

Where to grow and best uses

This species performs on well drained, often calcareous soils and tolerates dry conditions once established. It adapts to part shade or sun with some afternoon shade helpful in very hot sites. Use it in native plantings, erosion control on slopes, and low water landscapes where its winter flowers and berries add seasonal interest.

Planting and spacing

Place plants where soil drains freely and avoid heavy wet ground that causes root loss. Space specimens three to six feet apart to match the shrub s mature spread and allow room for clumping. Plant during a cooler season for root establishment in your region and mulch lightly to conserve moisture while avoiding soil saturation at the crown.

Watering and after flowering care

Water regularly through the first season until roots establish then reduce irrigation because established plants tolerate dry soil. Poor drainage causes decline so expect loss of vigor or roots in persistently wet sites. Prune for shape after flowering to preserve next seasons bloom and thin older stems to maintain a healthy multi stemmed habit.

Propagation and controlling spread

Propagate from seed, semi ripe cuttings, division of suckers, or by layering for new plants. The shrub can expand by basal shoots so control spread by removing unwanted suckers or by dividing clumps. Use division to reduce size or to produce new planting stock for erosion control and native garden beds.

Frequently asked questions

How fast does Texas Barberry grow?
Growth is moderate and the shrub reaches its typical three to six foot size over a few growing seasons. Rate varies with soil fertility, moisture and light.
Are the berries edible?
Berries are eaten by birds. Do not assume they are safe for people or pets. Check with local poison control or extension before considering any use as food.
What soil does Texas Barberry prefer?
It prefers well drained sites and tolerates dry, limestone or calcareous soils. Avoid heavy poorly drained soils that lead to root decline.
Can it be used for erosion control?
Yes. Its multi stemmed habit and tolerance of dry, shallow soils make it useful on slopes and in native plant erosion control projects.
When does it bloom?
Bloom occurs in late winter into early spring in its native range. Timing shifts with climate and latitude so expect local variation before scheduling pruning.
