Hardiness Of Hybrid Berries

How much cold will Phenomenal, Himalaya and Mammoth blackberries stand
in winter? Is it safe to plant where the temperature goes below 32
degrees?
These berries are hardy to zero at least, for they are grown in northern
parts of this coast where they get such a touch once in a while. They
have also endured low temperatures in the central continental plateau
States and eastward. Whether they can endure the lowest temperatures of
the winter-killing regions of the northern border cannot be determined
in California, for we do not have the conditions for such tests. The
berries are very hardy while dormant, and probably their value in colder
regions would depend rather more upon their disposition to remain
dormant than upon what they can endure when in that condition.
