John Boggan Very interesting, I’ve never seen a double-fllowered rex hybrid but there’s no reason why they shouldn’t exist. Come to think of it, I can’t think of any begonia from any of the Asian groups that have double flowers.
Mcleod Valley Greenhouses Sorry Ive not replied, James Missier, the rex line I was working with had a few flowers with extra tiny petals, so over the years I kept selecting and backcrossing these. The originals came from my mum, who was a begonias nut for years. They were not named back then, and so complex that the actual ID was obscure even then. Of course when I started to see results the excitement rose and a veritable sweat broke upon my weary brow, but I kept going. It’s all about the journey of discovery. These are addictive. About lowland growing I don’t know where you live, I don’t have any knowledge how they would do, but my summers are hot and dry. No mildew problems at all, so far. Cheers!
Mcleod Valley Greenhouses: Yes but have not sold any, just playing with it to see the best ways. The line also was selected for years to have flowers on top. I think the poor rex bunch have been a bit messed up with breeders not wanting to see flowers, or maybe the flowers were not long lasting so I understand this from a growers viewpoint. I wanted to change all that and have both long lasting flowers that were presented on top.
Mcleod Valley Greenhouses: John Boggan, thanks for your thoughts. Here is an experimental cross with tuberous. Only one or two in a thousand turned out to have decent flowers that lasted and were of quality.
