The choices for ramblers in the cold zones are somewhat limited. I have had good success with the Ayrshire group. Those do indeed ramble, everywhere if you let them. The blooms are white and pretty, but lack the lavishness of the Barbier roses. I think Roses Unlimited has one or two, some years. The Damask, Celsiana, should probably be thought of as a rambler. It throws out 15' canes. Then there is Lilian Gibson, which is huge, and will shade out anything growing beneath it.

I gather Dorothy Perkins and sports can be grown in 5. I have not attempted them. Among modern, repeat blooming ramblers, I have Alba Meidiland, IMHO one of the finest of modern introductions. It is hardy for me, but remains bushy.
