Berberis is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall found throughout the temperate and subtropical regions of the world (apart from Australia). Species diversity is greatest in South America, Africa and Asia; Europe and North America have native species as well. The most well-known Berberis species is the European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia. Many of the species have spines on the shoots and along the margins of the leaves.
Key Takeaways:
- Compact branches make a wonderful low hedge, barrier planting or single shrub accent.
- Look for varieties that grow tall or have a naturally upright habit. We promise you, it’ll be a brilliant display.
- It’s especially happy with other similarly tough plants such as the spreading juniper and Russian sage in this very elegant little border.
“A barberry that can be invasive in one climate, can be perfectly acceptable in another climate or region.”
