The roses you see are:
9. 'American Pillar' climbing into a cedar tree
(The name of each rose is a link to its description page on Help Me Find, a great rose reference site.
The Rambler Fence is a total mess this year, but it's a glorious mess with roses the size of haystacks. I didn't take the time to thin or train any of them this winter like I usually do ... and it is still a spectacular sight, with thousands of flowers and buds.
I won't torture you by mentioning the fragrance (which is lovely, BTW).
