For the record, I also think many existing PDF hybrids are pretty. Just really despised by most people.
I feel bad for future people trying to enter our hobby and they won't be able to find species plants because they were deemed "unsellable" or were "too difficult to grow at the wholesale level." The reductionist scientist in me gets really worked up over this. But I doubt that there is anything that could be done about it.
I don't believe that is how things will play out, not at all. Any genus that is experiencing growth in interest will also see an increase in availability of plants, be they species or hybrids. No matter how commercial growers approach the problems of production for any given species/grex, they are motivated to produce as much plant material as is feasible, and to distribute it at prices the market will bear. The things we hobbyists desire translate into motivational forces that come to bear on commercial producers. Time, however, is a major limiting factor, so it can take years for specific plants to make their way from a nursery lab (regardless of whether we are talking seeds cultured in lab, or tissue cultured clones produced in mass). People are scrambling to obtain N. edwardsiana, no matter what the source or how outrageous the cost, and yet folks seem to think source entities are "holding back" on the growers, to artificially inflate prices or some such nonsense. It takes a long time to produce a batch of tissue cultured plants and get them into a condition for sale. Anyone who knows how tiny Wistuba plants are realizes Andreas is pushing out merchandise as quickly as he can (some would argue TOO quickly), not withholding valued species in order to gouge buyers.
That said, availability of the newest darlings of the Nepenthes world will eventually reach a point where they can be had for sensible prices, and market demand will be more easily met. To suggest otherwise is kinda silly, IMO. Keep in mind as well that availability happens in cycles: a batch of plants leaves the producer, is bought up and then there is an apparent "drought", which someone -inevitably - claims is a new and terrifying trend indicating decline in species availability.
So, really the only thing we can do is keep up the demand for these plants...which I don't think will be a problem for most people on this forum .
So what you are really saying is that the very thing you first stated concern for, isn't actually a problem since you believe the CP community will continue to fuel the need for these plants, am I reading that right?! LOL
