That is exactly why I didn't focus on them; I don't have a suburban garden with the possibility for irrigation. I want to add companions for the roses,but finding plants that will accept these conditions does require some experimenting. Iris are a good bet, I think, since the native wild varieties are quite content.Surprisingly, delphiniums do well, too, as long as I remember to protect them from slugs when they are still short.
The nursery did get back to me-they have all of my list except Florentine Silk and Yaquina Blue (bummer).I'm going to take a quick look at their catalog again to see if any replacements for these two catch my eye...any suggestions?
