Can a rose bush change from pink to red?

[Dennis S]

I gave mom a pink climbing rose bush 30+ years ago that was never tended and just grew at the edge of the woods. When the pines were all cut, she rescued it and put the root ball in a bucket. Last year she replanted the roots and the roses just bloomed - they were all bright red, not pink.

Nutrients in the soil/water/dog piss/cat poop, etc.
Enjoy.

Possibly the bush had been grafted.

Most likely that and what survived the winter was the rootstock and not the climbing rose stem that had been grafted onto it.

Situation sounds more like like nutrients, or weather/environment/location (hot/cold/sun/shade/ground vs. pot/soil type) related.
The old pink climber was probably an own root rose, since those are usually pretty sturdy rooters, though a graft would explain a color change....
That was actually my first thought from just reading the subject line before clicking on it.
Roses can/will certainly change characteristics when shocked, so sometime in the next 30 years the truth will likely emerge.

It depends on whom she buried under it.
