Some of the primary 4-5 primary KO's say no fragrance, and some say mild. I have smelled all of them, and they all smell like cinnamon to me. Not strong whatsoever. A light cinnamon. It's actually kind of nice. Scarlet Moss is the same scent, to me.

I agree, the smell drifts & spicy floral in local store's containers .. a medium scent. My neighbor said my Knock-outs smell good in cold fall. The double-pink-knock-out has a better scent than red-knock-out.

I live in a pretty town founded in the 17c. that is a tourist destination. We used to have a huge variety of roses displayed in yards, on trellises, on split rail fences and tumbling over stone walls. They were many of the classic roses of the 20c. with 'Excelsa', 'Dorothy Perkins', 'Aloha', 'Coral Dawn', 'Betty Prior', 'New Dawn', 'Ballerina' and a variety of floribunda and hybrid teas as common landscape plants. Today most of these are gone; all replaced with this rose.

What can I say?

Sorry to hear that all those roses are now gone from your town...
The new generation seems to prefer low maintenance roses, etc...

I live in a bad area for blackspot and the other similar fungal diseases.
I planted highly disease resistant roses in our backyard because I want to stay away from chemical fungicides... Organic control does not work here...

mine stays much darker than most of the photos here.
it really is a more complex, darker bloom than the regular Knock Out, which I also love for it's remontancy, and the beautiful contrast between the shade of the bloom and the foliage.
Anyway, if you have regular Knock Out, and are thinking of getting the Double, but are afraid it is too similar, it is not and it is well worth the purchase.
It does love it's water. Don't try xeriscaping with it. This past year's drought in New England stressed it as much as the other roses (except regular Knock Out, which didn't seem to care as much). chris in ct.

Thank you. It's good to know that this rose is not particularly drought resistant.

The patent states the parentage is identical to the original Knock Out, which has the full detailed parentage here on HMF.

"The new variety of Rosa hybrida landscape shrub rose plant of the present invention was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was a seedling of the 'Bucbi' variety (U.S. Plant Pat. No. 4,225). The 'Bucbi' variety is marketed under the CAREFREE BEAUTY trademark. The male parent (i.e., the pollen parent) of the new variety was a seedling of the 'Razzle Dazzle' variety (U.S. Plant Pat. No. 3,995). The parentage of the new variety can be summarized as follows:

'Bucbi' seedlingx'Razzle Dazzle' seedling.

Such parental plants are the same as those used when creating the 'Radrazz' variety (U.S. Plant Pat. No. 11,836)."

'Knock out' and 'double knock out' have been updated to have the same parentage as listed in the patent.
