There are more than a few dwarf red barberries in the world so what makes ‘Crimson Ruby’ stand out?? Consistency is its strongest trait with a dense, compact rounded form that varies little, unlike plants such as ‘Crimson Pygmy’. Coloration is another strong point with deep, reddish-purple foliage that is as deep as any barberry selection and one that will not fade even during the hot summer months. This consistency and coloration make ‘Crimson Ruby’ arguably the best barberry for use in groups and edging and, like all barberries, it is incredibly tolerant and easy to grow, thriving in full sun.
