Berberis Mentorensis (Plant Patent No. 99). 
Is the result of a cross between Barberry Thunbergi 
and Barberry Julianae. It has very rugged, strong, up¬ 
right 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 Northern Ohio the leaves remain green until 
after the holidays, are dropped during the late win¬ 
ter, and new foliage appears early in April. Plants 
growing south of here retain their foliage much longer. 
In southern parts of the country, Berberis Mentor¬ 
ensis is evergreen. 
I ts most valuable attribute is its ability to withstand 
heat and drought. Few other shrubs or hedge plants 
are able to go without water and withstand intense 
heat as Barberry Mentorensis and look as well. During 
the hottest weather there is never any sign of wilting 
or burning, much to the amazement of everyone. 
Upright growth; easy upkeep (requires really no 
pruning), and its tenacious foliage, more than com¬ 
pensate for lack of berries. We recommend Berberis 
Mentorensis to you and claim it to be the best moder¬ 
ately priced and perfectly hardy hedge plant to date. 
There are 6 outstanding points of superiority about 
this Barberry: 
First —it is evergreen practically the year around. 
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 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! 
The Morton Arboretum 
at Lisle, Illinois, near Chi¬ 
cago, testing garden for 
shrubs and especially 
hedges, writes: 
The Mentor Barberry 
(Berberis Mentorensis) 
has been much discussed 
of late, and after several 
years’ trial, we are thor¬ 
oughly convinced of its 
hedge possibilities. A hy¬ 
brid of B. Julianae and 
B. Thunbergi parentage, 
it is fortunate in possess¬ 
ing the former’s erect 
habit and semi-evergreen, 
leathery dark green foli¬ 
age combined with the lat¬ 
ter's hardiness and vigor.

Fifth —combined in a foundation planting with ever¬ 
greens, it provides a beautiful and artistic contrast 
at very small expense and without elaborate prep¬ 
aration of soil. 
Sixth— Is not "choosy" about where it grows. No 
matter if you can't make other broad-leaf ever¬ 
greens, 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.
