Shrub · North Texas care guide
Berberis thunbergii
Nursery Pro tip: Color without flowers, and deer leave it alone thanks to the thorns. 'Gold Bonanza' stays a tidy mound with no pruning.
Compact mounding shrubs grown for foliage — burgundy 'Crimson Pygmy', gold 'Bonanza', and orange 'Sunjoy' types — 2–4 ft, deciduous, thorny, and about as tough and deer-proof as a shrub gets.
Full sun for the strongest foliage color; part shade dulls it. Any drained soil. Space 2–3 ft apart. The thorns are serious, so keep it away from walkways and play areas — and use them on purpose under a window.
Fall or spring. Hole twice the pot width, ball at grade, native soil, Root Stimulator, mulch. Wear gloves.
Weekly the first summer, then every couple of weeks. Drought tolerant once established.
One light spring feeding.
Late winter. It holds its shape naturally; shorten stray shoots to a joint. Hard renewal pruning works if it gets woody.
Root rot in wet beds. Some states restrict Japanese barberry as invasive because of its seedlings — it isn't a problem here, but the sterile newer varieties avoid the question entirely.
Color contrast in a foundation bed against gold ligustrum or green boxwood; good with ornamental grasses and Knock Out roses.
