I strongly suggest that L I Jane and John M exchange pollen of their jongheana and sincorana to produce a new primary hybrid with fantastic potential. I would gladly pay for the flasking for a share of the seedlings.
Crossing it with jongheana would be interesting; but, I removed the flowers today. It'd been out for some time and they were beginning to look tired. Besides, the front growths, including the one in bloom, belong to someone else now and they will be removed and shipped out next month.
