Feed stores...go to the yellow pages of the phone book, should be listed under "F" for feed stores I think? Look for stores that cater to chicken, birds, horses and dogs...usually they sell to agriculture or people that have a mini farm or stable. I'm not positive if there's a difference with the Kelp, but I've read great things about the Norwegian brand, so that's why I wanted to try it.

Don't know where to buy it but that should be an easy thing to knock off. The mirrors would be easy enough to find at Hobby Lobby or Michael's - some place like that. There are a gazillion types of wire - can't tell for sure what that is but it's a soft wire, easy to bend and it's a rather random design. They probably bent it around 2 or 3 different sized forms. I'd wing it and make my own. Here is a link that might be useful: Wire on Amazon

West Coast online rose venders include Heirloom in Portland and Rogue Valley Roses in Southern Oregon. Just north of you in Petaluma is Garden Valley Ranch, the rose farm formerly owned by Ray Reddell and later bought by Ron Robinson (formerly on Gardenweb as, if I remember correctly, lemecduc, or something of the sort). Have you tried calling around to various Bay area nurseries? Most of your choices are recent introductions which are still in commerce.

Mila - sounds like you have a plan, and I know what you mean about not wanting to wait to follow through on your plan. There's always room for more roses if you get creative! Glad the pictures helped you get tempted - they're all great climbers and you can't go wrong with any of the three you mentioned. Summers - for sure you'd have to finagle a way to attach the canes to the trees, and that's getting way too close to Quadra for my skin's sake. He's big and thorny, and between two trees he'd be just waiting to pounce. For sure you'd need another kind of support in addition to the trees, or he'd be flopping on your other roses as you mention. I used to grow my Quadra as a free-standing bush and he was at least 7' wide and aggressive with space. Can you stretch some sort of trellis or arch between the trees for extra support? He might not bloom as much in part shade beneath trees, but I'm all for giving it a try if that's where he is. I have Veilchenblau beneath a huge oak tree and it's pretty impressive (though it doesn't want to climb). Cynthia
