My sister-in -law said she has one and I just have never seen any knockout roses in anything other than red and pink.
Is there such a rose as a knockout / yellow?
Yes, there is a yellow. It's very pale, almost cream. Saw them at the nursery the other day. I wish they'd come up with a white one.
I knew someone would here would know.
Does anyone have a yellow one? do they preform as well as the reds?
I have a yellow one and, yes, it performs just as well as the red. It starts out yellow and fades to cream as the flower ages. There is a white rose that is similar to Knockout. It is called White Out. It also starts as a pale yellow and turns white. I don't believe it is related to Knockout, though.
I have White Out too. It does not act like a Knockout. Mine is eaten up with blackspot.
