ROSE OF PERU (Black Prince). Table variety, also 
used for wine. Large, loose bunches of big, round, dark- 
purple berries. Vigorous growing vine and excellent for 
arbors. Fine eating grape; flesh dark, juicy, sweet. Sep- 
tember. 
SULTANINA ROSEA (Pink Thompson). Table and 
raisin variety. A grape which is exactly like the Thomp- 
son Seedless, but the berries are colored’ a beautiful blush 
pink, deepening to red in the sun, and in some districts 
they ripen with early Thompsons. A curiosity for the home 
garden, which also dries out heavily as a raisin. July to 
September. 
AMERICAN GRAPES 
Vitis Labrusca is known as the American Grape, and 
the Concord is a typical example. It is grown extensively 
in the States of New York, Pennsylvania, Michigan, Ar- 
kansas, Missouri and Iowa, and the fruit is sometimes 
known as “slipskin” grapes; in fact, they can be distin- 
guished from the Vinifera or European varieties by. this 
characteristic alone. They are also known as Fox Grapes. 
When the early American Colonists tried to grow the 
varieties they brought from Europe in New England and 
the Middle Atlantic States, they failed and turned to the 
native wild grapes of the region. We know today that this 
failure was due to Phylloxera, which on the Atlantic Coast 
attacks both the canes and the roots, whereas in California 
only the roots are affected, and to mildew, which is now 
universally controlled by dusting the vines with sulphur. 
However, American Grapes are more resistant to mildew 
than European varieties, and they also require much less 
heat for proper ripening. These American Grapes are 
descendants of these native wild grapes of New England 
and the Middle Atlantic States. Much of the early work 
of hybridization and. selection was done by Thomas Jeffer- 
son at his estate of Monticello, in Virginia. Seventy years 
or so ago, when Phylloxera was about to wipe out the 
wine industry in France, science turned to native wild 
grapes of America for root stock resistant to Phylloxera. 
Fortunately, here in California Phylloxera spread much 
more slowly, and with our strict quarantine laws is now 
confined to certain older grape growing sections of the 
State. All these American varieties are adapted to training 
on fences and arbors, and do well anywhere on the Pacific 
Coast, except desert sections, doing particularly well in the 
coastal sections of California; in fact, they seem better 
adapted climatically than some of the European varieties 
to coast climate.
