Cold Hardiness and Disease Resistance
Some V. riparia vines have been known to withstand temperatures as low as -57 °C (−70 °F). The foliage is typically resistant to mildew and black rot, and the roots resistant to phylloxera. The berries however, are often sensitive to mildew and black rot if the vine is exposed to prolonged wet and humid conditions.

Famous quotes containing the words cold, disease and/or resistance:
“Is this a holy thing to see
In a rich and fruitful land,
Babes reduced to misery,
Fed with cold and usurous hand?”
—William Blake (1757–1827)
“In a country where misery and want were the foundation of the social structure, famine was periodic, death from starvation common, disease pervasive, thievery normal, and graft and corruption taken for granted, the elimination of these conditions in Communist China is so striking that negative aspects of the new rule fade in relative importance.”
—Barbara Tuchman (1912–1989)
“How is freedom measured, in individuals as in nations? By the resistance which has to be overcome, by the effort it costs to stay aloft. One would have to seek the highest type of free man where the greatest resistance is constantly being overcome: five steps from tyranny, near the threshold of the danger of servitude.”
—Friedrich Nietzsche (1844–1900)
