Companions: White, Gray, Herbs?
I was beginning to turn my thoughts back to rose companions, and I realized that I mostly have bluish purple companions. I would love to add some white or silvery gray to the garden. I've really wanted to add some sort of white umbillefer, but I've been afraid that they are all a little too vigorous. The other day, it occurred to me that I like to grow cilantro, and I get frustrated at how easily it bolts in the heat, but the flowers are white, and I could just grow my cilantro in with the roses. Then I got to wondering, would cilantro be a good match culturally for the roses? I know a lot of people grow herbs with roses, but is cilantro a good choice?
I would also love to hear about your favorite white, gray, or herbal companions (particularly, if they magically did not take up any room that I could use for yet another rose!).
