Many nurseries use what is considered a generic safe range. I experience the opposite problem that nurseries list plants zone 5 and up, even though a plant will grow successfully in zone 4 or lower. Nursery management simply does not take the time to seek and list correct zone information. Some nurseries are getting better at this, though. For those of you in colder zones, Joy Creek still uses, or at least was last time I checked in fall of last year, the generic safe range for zones, so I'm sure the high end isn't always right, either.

I know Dan from Brushwood is working with Edith Malak , President of ACS, to list the correct growing zones. on his site.

American Clematis Society had been collecting data about growing zones from their members, isn't available unless you join.

Clematis on the Web is collecting zone information from clematis growers around the world and will be publishing the data at some point. The entire industry will benefit from their efforts, I'm sure, and I expect it will be available without having to pay for it.
