Lightly pruning back my two huge light pink Knock Outs that turned into monsters this year - due to lack of pruning since I planted them 3 years ago - and in the back of one are neon red blooms. I haven't worked my way back there yet so I don't know if the strong vertical growth with the red blooms is coming form below the soil level, but I'd bet the pink was grafted on to red rootstock. Is that common with Knock Outs? Pink blooms in front, red in the back. The rose's version of a mullet, haha.  Give me land, lots of land, under starry skies above. Don't fence me in. |

| AH! You seem to have some thriving Dr. Huey rootstock there. https://www.helpmefind.com/gar... To really eliminate it, you will have to go all the way down to where that growth branches off from the roots. You will be told that you must rip it off ... and I think that's probably ideal -- but I personally don't have The Incredible Hulk wandering in to assist . . . So I have in the past resorted to cutting off that root. (Once I got down to it, of course.) If you choose to ignore it, you will eventually have a huge once-blooming rambler which is lovely in the spring, and then, typically, blackspots all to Hell-and-gone. |

| Does Dr. Huey bloom this late in the season? |

| hmm...I wonder if the two can coexist if I prune to keep the Dr. Huey in control? It's rather lovely! I may try putting up a trellis in the back where it's coming up, and then pruning off any other shoots that bloom that color when they bloom. I have to go take a better look (I was a bit heat exhausted before) but I thought the growth was coming from above the bud union. It's still in the mid 80s here so I guess the roses think it's summer! Well, I just double checked and the stem is coming out from above the bud union. I wonder if our cool nights influenced the color of the new blooms? The form is also identical to the pink ones. Not sure what's going on but it's pretty. I'll keep an eye on it, thanks for the info! Give me land, lots of land, under starry skies above. Don't fence me in. |

| I'm with Vaporvac, that doesn't look like the Doctor to me. If it was DH and it came up last year, in zone 6, it would have bloomed already. If it came up this year it wouldn't have bloomed at all until next spring. It does look like a reversion of the pink KO to the red KO though. I once had a pink sport show up on my red KO too. Do check the base of the plant and see where that cane is coming from just to be sure. |

| these are not grafted. That is also not DH. And my pink knock out does that too. It has one branch that blooms w red flowers, it did it last year and this year both. |

| Are some KOs grafted? Or are they all or ? Simple on a Schedule |

| They can be grafted or own root depending on what supplier they came from. My Appleblossom Flower Carpet has one branch that blooms red every year too. Like I said, it's just a reversion of the sport back to the original variety. Fun and interesting but nothing to worry about. |

I just assume they are all grown from cuttings because I ordered some yellow KO in the mail and they came about 6 inches tall in a tiny pot. I was pretty disappointed, but they grew like weeds, I couldn't believe it! Maybe some are grafted, but my red 'branch' is up on the bush, not coming out of rootstock for sure. so who knows. I too think just a revision fluke  |

| Pink Knockout is a sport of Double Red Knockout, and it quite commonly reverts back to the parent version. I almost guarantee that this is a reversion and not rootstock. Nothing to worry about. I've had it happen multiple times (back when I still grew KOs). If you don't like it, prune it out. If you do, root the offending stem and you'll have a free Double Red KO. John |

I actually like the red better then the pink! The pink is extremely floriferous though. I love that they are both on the same plant... Give me land, lots of land, under starry skies above.
