Peach trees in Western Washington?

I live about 20 miles NE of Seattle at the base of the Cascades and want to try a couple peach trees. We get about 48 inches of rain a year. Any particular varieties people have luck with in the area? Frost Peach and Avalon Pride seem to be the most recommended/common. I'll get dwarf or semi-dwarf and put them on the south side of my barn. My soil isn't great but I'm working on it!

I posted an article with all of Douglas Bullock’s recommendations for fruit trees in Seattle.

In short, his recommendations for peaches were Frost, Avalon Pride, and Q18.

At 20 miles NE of Seattle you might be a bit cooler than Seattle, though. I'd check out this PDF from Wash St. University on cold-hardy trees & shrubs. It's meant for Kittitas County but if it works there, and in Seattle, that's a good bet. The only Peach I could find listed in that pamphlet is Avalon Pride.

Also, try calling up Raintree Nursery and asking their opinion - they've got plenty of knowledge they love to share.

I live in Oregon's Coast Range- similar to your climate . I've had great success with Charlotte, Indian Blood and Frost peaches- all delicious and all resistant to leaf-curl disease. I also grow Patio Peach in big pots in my greenhouse. Be sure to get leaf-curl resistant varieties ONLY. I had poor luck with Veteran peach (which is not resistant). Because I quit spraying copper (organic control for leaf-curl) for a few years, the tree died from this disease. Indian Blood is my favorite peach- they ripen in early October, have juicy, purple-cream flesh and they are resistant to bacterial canker, too. Raintree and Burnt Ridge carry this one, but I could send you seeds from my tree if you like, just PM me. (Peaches usually remain true-to-type from seed.)
