Sundowner is a nice rose. My dad has had one in his garden in Whitby Ontario for several years now and it overwinters nicely here with minimal protection (ie: against a south facing wall).

UNBELIEVABLE!!! Zone 5. Got this in bare root bag for about $4 in Walmart spring of 2012. I planted bare root in wooden whiskey barrel and then waited . . .When it seemed like this rose wood never form blooms: voila! in July or August I had beautiful deep orange fragrant blooms. It looks a lot like "Cali Sue"'s picture posted here. And added plus: It overwintered just fine in that whiskey barrel uncovered, and is now sending out new leaves. You won't be dissapointed.
