Gi CNew Barberry 
Drought Resistant Mentor Barberry 
The Morton Arboretum at Lisle, Illinois, 
near Chicago, testing garden for shrubs and 
especially hedges, writes: 
The Mentor Barberry (Berberis Mentor- 
ensis) has been much discussed of late, and 
after several years’ trial, we are thoroughly 
convinced of its hedge possibilities. A hy- 
brid of B. Julianae and B. Thunbergi par- 
entage, it is fortunate in possessing the 
former's erect habit and semi-evergreen, 
leathery dark green foliage combined with 
the latter’s hardiness and vigor.

Two-year-old 
Mentorensis 
Barberry 
























BERBERIS MENTORENSIS (Plant Patent No. 99.) 4 
It has very stiff, upright growing branches and quite formidable 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 tem= 
peratures go hand in hand with lack of rain, it never shows any signs of rust — 
and discoloration of foliage 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 con- — 
sidered the finest evergreen plant for hedges. It is amazingly satisfactory — 
growing around airways or close to dry foundation walls, and does an out- — 
standing job in city gardens, either in single specimens or as a hedge. tsa 
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 andi 
clean looking, upright in growth, easy upkeep (requires really — 
no pruning), and its tenacious foliage, more than compensates ~ 
for the lack of berries. We heartily recommend Berberis Men- — 
torensis to you. For hedge use plant in single rows, 12 to 15 __ 
inches apart for best effects. 
First—It is evergreen practically the year around. Think what that 
means. 
Second—lts 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 q 
formidable 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 pro- — 
vides a beautiful and artistic contrast at very small expense and 
without elaborate preparation of soil. 
a 
Sixth—lIs 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. 
Ultimate Height—5 to 6 feet.
