As its common name suggests, much of the attraction to 'Divinely Blue' is its beautiful blue coloring. This flat-topped plant has a growth rate of three to six inches a year and at maturity will be six feet tall and only three feet wide. New growth comes in pale, gray-green and creates a lovely contrast to the darker blue foliage, giving the plant depth and interest. This selection also is reliable in colder climates, holding up well under snow cover. In addition to its blue foliage, this plant was named for Bill Devine, a retired propagator from Angelica Nursery in Maryland. Zone 6 - 7
