Barberry Bush Shocked Every Gardener—Here’s What Science Can’t Ignore If you’ve ever tended to a garden, chances are you’ve stumbled across the barberry bush—a vibrant, thorny shrub adored for its striking yellow flowers and red berries. But in recent years, this once-beloved plant has sparked surprising controversy among gardeners and botanists alike. Known scientifically as Berberis vulgaris, the barberry bush has intrigued scientists and horticulturists due to its unexpected ecological and health impacts—truly a plant that’s far more complex than growers realize. ### What’s So Shocking About the Barberry Bush?
