I sw a nice specimen of it on the show - with good bloom count for this species - but it was dropping flowers in front of judges until all of them were on the table...Gorgeous color.

Thanks, that looks to be it.

Mine is not reluctant to flower, fortunately (it is currently enjoying a summer outdoors). So far my attempts to use it in cross-pollination have not resulted in any seed.

Good Luck. It is possible - but who knows - may be outside it is too hot or not humid enough or you need to sing a lullabye...Plus - if you are not selfing it but trying to cross with another species... there is always a challenge.
