Cistus- looking for a hardy rock rose - Knowledgebase Question

I am looking for a hardy rock rose. The site is in MA (zone 5) inside a walled garden. Although it is a protected area I am concerned about the winter temperatures. Can you recommend a more cold hardy variety?

Sadly, the hardiest I know of is still only hardy into zone 7. Based on my experience, that is too much of a discrepancy to overcome, even if planted inside a sheltered walled area. I'm sorry I can't be more encouraging.
