Does anyone have any experience growing this rose on its own roots? I have heard rumors that it does not do well on its own roots. I saw an own root plant of GdD at the San Jose Heritage Rose Garden a few years ago that seemed to be struggling.

I have own root plants of its parents, Jaune Desprez and Souv. de la Malmaison, that are thriving in my garden, so it seems likely that its hybrid should also do well on its own roots. I had intended to purchase a grafted plant from Pickering, but they have not listed this rose in their catalogue for several years. GdD is available from both High Country roses and Rogue Valley Roses on its own roots. Can anyone help me?
