Picture of a Barberry Shrub. Picture by OpioÅa Jerzy. Image use (cc2) The Barberry Genus has both deciduous shrub and evergreen shrub species. The deciduous species ( such as Berberis thunbergii, and Berberis vulgaris) are popular for their attractive autumn color sequence, turning pink or red before falling.
Depending on the variety you get, many will have spring flowers that are fragrant. The summer foliage is outstanding and many barberry's will produce berries in the Fall as well as change foliage colors. Once established the barberry shrub is one of the lowest maintenance shrubs you will have in your yard. You can trim it to maintain it's shape and size or you can let it grow freely.
