Susan, I really like the Apple Blossom achillea, and I have never been a fan of yarrow! Maybe because I have never seen a pink one until now. Is it really drought tolerant like other yarrows? I have a few scattered white yarrow here, and I wouldn't mind if it wasn't here. It's just not pretty to me, but it does bloom on almost no water, and seems to hold up well. I had yellow in Utah, and it was okay, but invasive. My Dad has a problem with a yellow one at his house. He was joking that he was going to put an add in the paper to sell it, stating that it likes Roundup and dog urine for fertilizer.
That pink one though is really nice! If it can survive on the hillside here, I will get some!
