Leuthardt’s New Hybrid Grapes are grown as an Arbor in 
mixed varieties against a wire trellis, lending a most decorative 
vine display. These early bearing vines, with their extremely 
delicate, lacey trimmed, soft green foliage—an abundant yield 
of richly flavored, highly colored fruit, combine the best 
American and French traits. - 
SUPERIOR GRAPES OR HYBRIDS 
It is astonishing how the public together with the majority 
of nurserymen are unaware of the tremendous progress that has 
been made during the last few decades in improving the various 
strains of grape vines that will grow in the rougher and colder 
climates of this country. 
Throughout North America, from the eastern side of the 
Rockies to the Atlantic shore, grape vines are grown belonging 
to several families or species native in the different sections of 
our vast country. Vitis Labrusca; V. Aestivalis; V. Lincecumii; 
V. Riparia; represent some of the parents of the Concords, 
Niagaras, and other varieties offered in the market. But, the 
grapes they yield have an unpleasant foxy flavor, tough skin, 
coarse seeds, and other inferior qualities that make them un- 
desirable either as table or wine grapes. 
The Caucasian Grape (Vitisvinifera) is far superior to our 
native grape. This grape family, evolved in the milder parts of 
Europe and Asia, whence they were brought to California where 
they procluced the excellent grapes that are familiar to the aver- 
age American. However, these species have not the necessary 
make up to withstand our sub-zero weather and succumb dis- 
astrously to the diseases prevailing here; while our hardy Native 
Grapes remain immum. 
The North American grape vines which were imported to 
Europe to be grown and tried in climate similar to ours, brought
