BERBERIS Barberry 



A large group of deciduous and evergreen shrubs which, where all species 

 are hardy, presents a great many fine garden forms differing widely in habit, 

 texture, and general aspect. Harsh local climate, however, seriously restricts 

 their general use in most of New England. Here are listed some of the forms 

 which have been found to be more satisfactory in the northeastern part of 

 the country. 



BERBERIS AMURENSIS var. JAPONICA Hakodate Barberry 



A ten-foot deciduous shrub which may be used as a substitute for the 

 Common Barberry. Unlike B. vulgaris this Asiatic variety has straight, up- 

 right branches from which in late autumn the large, attractive fruit clusters 

 hang in much the same manner as do the flowers of Enkianthus campanulatus. 

 Its leaves, too, are of a lighter shade of green. Like the Common Barberry, 

 this plant naturalizes readily in open woods. 



BERBERIS BUXIFOLIA var. PYGMAEA Dwarf Magellan Barberry 

 A dwarf, compact, thornless form of one of the hardiest species of evergreen 

 Barberries. Something for the rock-garden collection. 



Berberis candidula 



A dwarf Barberry for the rock garden. The shining leaves with few spines 

 and white undersurfaces are borne on smooth branchlets. Related to B. verru- 

 culosa. 



Berberis dictyophylla CHALKLEAF BARBERRY 



A deciduous species with little garden value beyond the possible winter 

 effect in wild plantings of its white young wood. So used, it would compete 

 with some of the bloomy-stemmed Raspberries. 



Berberis Julianae WlNTERGREEN BARBERRY 



A top-tender, upright, evergreen shrub, the branches of which will seldom 

 survive enough inland New England winters to attain their potential height 

 of some six feet. Its narrow, spiny, persistent foliage and blue-black fruits 

 make it worth planting in warmer areas of the North. 



BERBF.RIS KOREANA KOREAN BARBERRY 



Now that it has been determined definitely as not being a host to the wheat 

 rust, this thick-branched, upright, six-foot, deciduous shrub will probably be 

 more used. Because of its bright-green, rounded leaves turning to red in 

 autumn, and its long-persistent red fruits which follow the yellow flowers of 

 May, it should become a shrub for more general planting. 



X BKRBERIS MENTORENSIS 



A garden hybrid of recent introduction which, because of its somewhat up- 

 right branching and large, long-persistent leaves, is being advocated for hedge 

 making.
