my in-house rose expert says you can plant pretty much anytime that the ground isn't frozen or too dry. She suggests three interesting yellow roses: Mermaid, Alister Stella Gray, and Alberic Barbier. Alberic, apparently, is tender in cold climates. A couple places to check out for sources and info: Bramble and Rose in Yachats, Oregon, is right on the coast, very knowledgable and friendly people; also Heirloom Roses in St. Paul, Oregon; and Vintage Gardens in Sebastopol, California.

good luck.

ps -- we've had good success with Jude the Obscure, another David Austin rose with huge pale apricot blossoms and an incredible fragrance.
