Sunjoy Gold Pillar® Barberry

Sunjoy Gold Pillar® is the Sunjoy series name for Berberis thunbergii ‘Maria’, an upright Japanese barberry with a narrow columnar outline. Golden-yellow leaves and red new growth create a bright display that shifts to orange-red foliage in autumn. ## Form and Foliage [Spring Meadow Nursery’s breeder profile](https://springmeadownursery.com/plantfinder/sunjoy-gold-pillar-03870) identifies ‘Maria’ and describes a mature shrub about 3–4 feet tall and 2–3 feet wide. The [plant patent](https://patents.google.com/patent/USPP18082P2/en) confirms the cultivar name and columnar habit. Yellow spring flowers add a secondary seasonal feature. ## Placement Plant in full sun and well-drained soil. The breeder lists USDA zones 4–8 and notes that established plants tolerate dry conditions. Use the narrow form as a vertical accent in a border, foundation planting, or small hedge, leaving room for its natural spread instead of clipping it tightly. ## Seasonal Interest Red new growth contrasts with golden foliage, followed by orange-red autumn color. Spring flowers are small and yellow; the foliage remains the main ornamental feature. ## Maintenance Water while the shrub establishes and during extended dry weather. Its columnar shape needs only light pruning, if any. Trim in late spring or early summer when needed, avoid cutting into thick old stems, and wear gloves when handling spiny branches.
