For hardiness ratings for Grevilleas, a good general
reference would be the catalogue listings for Suncrest
Nurseries, which lists cold tolerance for the species
that they grow. The nursery list for Western Hills
Nursery would also list grevilleas which are among the
more cold tolerant, as they get regular cold winters
there, and anything which survived the 1990 freeze in
their area might be good candidates for USDA Zone 7
climates, as I think they got down to 15F there that
winter.
Sorry that I can't help with direct experience, as we
just don't get that cold here in Berkeley, with the
lowest temperatures in my own garden down to maybe
24/25F in the 1990 winter's freeze. I can say that
one of my favorites, Grevillea 'Robyn Gordon' is
suspect at temps much below 32F, and that G. victoriae
was not damaged here that winter. Most of the
temperature listings in Suncrest's catalogue list
probable temperature frost resistance down to 15F, as
they did not get below that in 1990.
