I saw these at Lowes. Really interesting. I'm guessing that its just two different varieties budded onto one rootstock. If you only have one color at the moment, I would guess either one of the grafts has died, or the second rose blooms at a different time than the first.

Yeah i noticed some at work. I saw on a few they had a label strip on one of the thicker canes(right word here?) they'll have a label with two names with a / between. Those multigraft tree's I've also seen, I did not notice a name label on those though.

Three or four years ago, Park Wayside were selling tree roses that were pretty tall with an upper graft (several insertions into the scion) and then a foot or so lower on the stem, the same roses grafted down there as well.
