Sunjoy® Mini Maroon® Dwarf Red Barberry

Sunjoy® Mini Maroon® is a compact Japanese barberry with deep purple-red leaves and a naturally tidy, mounded shape. The Proven Winners cultivar profile identifies the selection as ‘NCBT1’ and lists yellow flowers, USDA zones 4–8, and a mature size of about 2–3 feet tall and wide. ## Form and Foliage The [Proven Winners profile](https://www.provenwinnerscolorchoice.com/product/sunjoy-mini-maroon-barberry/) describes the exact cultivar, PP30330 patent, purple and red foliage, and minimal pruning needs. It also notes deer resistance and drought tolerance once established. The [North Carolina Extension Sunjoy guide](https://plants.ces.ncsu.edu/plants/berberis-thunbergii-sunjoy-group/) explains that Sunjoy selections were bred for sterility and do not self-seed. ## Placement Grow in full sun for the strongest foliage color and use well-drained soil. This small shrub works as a low hedge, border accent, container specimen, or repeated planting in a sunny bed. Its thorny stems need clearance from walkways and areas where people regularly reach into the planting. ## Seasonal Interest Purple-red leaves provide color through the growing season, with fall listed as a season of interest. Small yellow flowers add a spring detail. ## Maintenance Water consistently during establishment and during prolonged dry periods. Once established, the breeder lists drought tolerance. The naturally compact habit needs little pruning; trim after new growth appears if shaping is needed, and wear gloves around the spines.
