Concorde Japanese Barberry (Berberis thunbergii 'Concorde') has pretty yellow flowers during spring, but no one seems to notice when compared to its outstanding burgundy foliage! This deciduous 3 season gem stays small, making it perfect for that formal garden or entryway, where its rich color only gets more intense through fall. However, Concorde Japanese Barberry is not pretentious, and can be put in the garden where it will look fabulous beside companion plants like Rhododendrons and Blueberry bushes.
