A New Bader Ie Y 
Drought Resistant Mentor Barberry 
BERBERIS MENTORENSIS (Plant Patent No. 99.) 
It has very stiff, upright growing branches and quite formidab!e 
thorns. Its foliage is heavy and thick, and of perfect color—a 
green as dark as the Japanese Yew. In hot and dry seasons or 
in localities where high temperatures go hand in hand with lack 
of rain, it never shows any signs of rust and discoloration of foli- 
age no matter how hot or dry it may be. Ultimate height about 
five feet. In Ohio the leaves remain green until after the holidays. 
Plants growing in Kansas, Oklahoma, Utah, and the Southwest 
retain their foliage, and there Berberis Mentorensis is evergreen 
and considered the finest evergreen plant for hedges. It is amaz- 
ingly satisfactory growing around airways or close to dry foundation 
walls, and does an outstanding job in city gardens, either in single 
specimens or as a hedge. Its unusual ability to withstand heat and 
drought is nothing short of wonderful. During the hottest and 
driest weather there is never any sign of wilting or burning, much 
to the amazement of everyone. Always good and clean looking, 
upright in growth, easy upkeep (requires really no pruning), and 
its tenacious foliage, more than compensates for the lack of ber- 
ries. We heartily recommend Berberis Mentorensis to you. For 
hedge use plant in single rows, 12 to 15 inches apart for best 
effects. Ultimate height, 5 to 6 feet. 
First—It is evergreen practically the year round. Think what that means. 
Second—its sturdy, erect growth carries a thick dark green foliage right 
down to the ground. Is never bare-legged. 
Third—When used for a hedge, its thorny, strong growth forms a formid- 
able barrier to man or beast. 
Fourth—Needs no pruning. It is of erect growth which becomes dense 
when the plant is three or four years old. No upkeep! No pruning! 
Fifth—Combined in a foundation planting with evergreens, it provides a 
beautiful and artistic contrast at very small expense and without elab- 
orate preparation of soil. 
Sixth—ls not ‘‘choosy’’ about where it grows. No matter if you can’t make 
other broad-leaf evergreens, such as Azaleas and Rhododendrons, thrive 
in your soil, this new Barberry will. It is equally at home whether it is 
acid or alkaline soil.
