Hello All, I’ve been away awhile due to life but am trying to get back into roses and hybridizing. I recently obtained two Gigantea species roses from High Country Roses. I live in Zone 7a/6b, so I was thinking of potting them and bringing them indoors in the winter. However, would they be too big to pot? I know they can grow quite large (which is the goal in introducing their genes) but don’t want to risk them being killed by our mercurial winters in East TN. Thoughts?
At least grafted R. gigantea could bloom in an unheated greenhouse, even the potted plant is very small. No problem.
