Berberis 'Golden Abundance' (Golden Abundance Oregon Grape) - This is a large, dense evergreen shrub to 6 to 8 feet tall by 8 to 12 feet wide. It has large compound glossy green leaves and an abundance of yellow flowers for several weeks in spring. The flowers are followed by deep purple berries that are attractive to birds. Plant in full sun to light shade and water deeply on occasion or give more regular irrigation. Hardy to 10 degrees. This cultivar was selected by Lee Lenz at the Rancho Santa Ana Botanic Garden who described the plant as a chance hybrid between 3 different Mahonia (the older name for Berberis) species, Mahonia piperiana, M. aquifolium and M. amplectans. Rancho Santa Ana Botanic Garden filed for a patent on it on June 4, 1971 and U.S. Plant Patent 3,332 was awarded on May 15, 1973. This was the first patent on a plant selection granted to a California botanic garden. Lee Lenz felt this plant merited attention as it was more vigorous and upright than its parents with dark glossy green leaves and larger terminal inflorescences held in great abundance as well as many lateral inflorescences produced along the stems. He also noted that after flowering it produced "numerous and drooping racemes of globose, purplish-blue fruit with a bloom." This plant has been in cultivation since the early 1970's and has proven itself a great hedge or accent plant in gardens from Seattle in the north to the heat of the central valley of California (where is should be given some afternoon shade) and all along the coast of California.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have observed it in. We also will incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing Berberis [Mahonia] 'Golden Abundance'.
