The Ure pear has been hardy for me for 2 years now, even under very
stressful conditions of drought and grasshoppers eating almost all the
leaves. The pear Early Gold, an open pollinated seedling of Ure, is
supposedly a bit hardier, a bit better quality, and less susceptible to iron
chlorosis, has also been hardy at my site.
