Tetraploids to Cross with Native Flame Azalea?
I have native flame azaleas (R. calendulaceum) on my property, and one of them has flowers that stand out because they are so brilliantly orange! I think it might be fun to cross this plant with other azaleas, but as I understand it, my native flame azalea is a natural tetraploid and it won't easily cross with most azaleas because they are diploid.
I starting looking for a list of tetraploid azaleas, and I am finding that it's not like daylilies where they are all classified as to whether they are diploid or tetraploid ... I guess with azaleas it's just assumed they are all diploid unless stated otherwise. Does anyone here know of a list of tetraploid azaleas? And might these tets be crossed with R. calendulaceum?
