Cabernet Barberry
Rich Wine-Purple Color All Season
Cabernet Barberry (Berberis thunbergii 'Cabernet') pours on the deep, saturated wine-purple color that makes a border feel rich and intentional. Its compact, rounded habit holds the dark burgundy tone from spring through fall, when it warms to red, and it asks for almost nothing in return. Thorny, deer-resistant, and drought-tough, it's a dependable dark accent for sunny Lakeville, Blaine, and Apple Valley landscapes.

Landscape Uses
Use Cabernet as a low hedge, a foundation accent, or a dark foil for gold and green foliage and bright perennials. The thorny stems double as a deer deterrent and informal barrier.
Best Time to Plant
Plant in spring or early fall while temperatures are cool and moisture is steady so roots establish quickly.
How to Plant
Dig a hole twice as wide as the root ball and just as deep. Set the crown level with the soil, backfill, water in well, and mulch 2–3 inches deep, keeping mulch off the stems. Full sun keeps the wine-purple deepest.
Watering
First Year: Water deeply 1–2 times per week to establish the roots.
After Year One: Water only during prolonged drought. It's highly drought tolerant once established.
Drip Irrigation: A drip line gives efficient, low-water moisture.

Is Cabernet Barberry Right for Your Yard?
Choose Cabernet for a hot, sunny, well-drained spot where you want season-long dark color with zero fuss — it laughs at drought, poor soil, and deer. Full sun keeps the purple deepest; in shade it fades toward green. It's not a fit for wet, poorly drained ground, and the thorny stems make it a poor pick right beside play areas or walkways. Note: Minnesota is phasing out Japanese barberry sales in the coming years, so check current availability rules if you're planning a large future planting.
