I think I've grown every variety of Knockout there is and yes, they sure do get bigger than what they (Conard-Pyle) claim then do, at least here in the South.
I'd go with someone's recommendation above for pots and use the Drift Series, a much smaller-growing type(s) but with the same Knockout features. My favorite is Peach as its flowers tend to change colors through the season and each color can appear on the plant at any time; quite a sight to behold.
Great ideas for pots, Larry. I'd definitely work with your suggested filler and spiller, too! I wasn't familiar with those terms but sure do like them!
Thanks for the write-up! And the pics are great!
