A huge, easy family of evergreen and deciduous species and varieties, berberis will grow almost anywhere.

The most popular leaf-shedding kind is Berberis thunbergii (Crimson Pygmy Barberry, Rose Glow Barberry, Intermedia Redleaf Barberry, and Thornless Barberry). Barberry are undemanding shrubs, many have fiery fall leaf tints, bearing yellow or orange spring flowers. Hardy to -13 degrees Fahrenheit, they can resist icy winter winds.
