I am a new one to rose gardening but like more contradicting colors when I plant roses next to each other but that's just my own preferences. The blushing is pretty but it gives of a pink tent as well. if you are wanting your colors to blend a little, yes, those two would do well. I would like something more like a World War II Memorial Rose next to a double pink....maybe an orange too. LoL but I love the contrast. Have fun with your project! We have some lovely rose gardens & maybe someone who has more experience will chime in. I am a newbie with roses!

My next door neighbor's Knock Out is about 4-5 fttall and 3.5-4 ft wide, whereas my Double Knock Outs are, at best, 3x2.5. Of course, my KOs are a couple years younger than my neighbor's, but I don't ever remember her KO spending much time at all in the smaller ranges. It grew up very quickly--so I conclude KO is an inherently taller and wider bush. However, as momcat51 noted, the KO's don't seem to mind being cut back considerably, so if you don't mind having to make periodic prunings, go with the form you like the best. Kate

Here is my Shamrock. Honestly, I'm completely disappointed by this plant's growth habit. Also, being overwintered in a pot it has only handfull of blooms on it. Miyama yae Murasaki has a very similar looking flowers, but it's now literaly covered by blooms beside being a nice tight compact shrub. In-ground, not in a pot. Shamrock is my first candidate for the door.

Many people will say to you that you don't need to deadhead Knock Out roses. They are shrub roses and will drop their petals and clean themselves up pretty good. There are 9 double red KOs in our front flower bed that were there when we bought the house. Last year they only bloomed sporadically and didn't have what I'd call a nice flush. This year I fertilized and had a beautiful flush on all nine bushes. Then I tried an experiment. I deadheaded five of those bushes and not the other four. The five I deadheaded are covered in blooms with their second flush but the four I didn't deadhead have only a few blooms on them. Deadheading them is a pain but I will certainly deadhead them from now on.
