On the Gardenweb rose forums there are several threads that may interest folks looking for sources for infusions of new traits.
On Antique Rose Forum, there’s a thread about the Viru Viraghavan hybrids that will be available next spring. Several clinophylla hybrids may have the potential to survive with very wet roots; could this be a step towards hydroponic roses?
There are also R. gigantea hybrids that I look forward to seeing.
On the GW Gallery there are two threads: one with a photo of a deep yellow (apparentely substance filled petals) of Golden Threshold, and a second of the species R. gigantea.
Thought you might be interested.
