...I thought you all might like to have a real-life report on these. They are sort of new this year, so I bit the hook and tried some.

So far, I wouldn't say I'm knocked out. :)

I have one yellow, and about six whites. They are really limping along. The leaves are not looking well at all, and they are not putting on a lot of new growth. Two or three of the whites look like they might do OK, but the rest are downright embarrassing. The yellow is hanging in there, I guess, but not blooming so much. I bought two other yellows for a couple of neighbors, and they promptly bit the dust. Double-embarrassing, after I had bragged about the hardiness of knockouts.

For comparison, I also bought about 15 red double knockouts (to line a fence) at about the same time. These are kicking butt! Got two pinks as well, and they are doing almost as well as the reds.

So, my experience has been: Red and pink = good. Yellow and white = sketchy.
