Hello Gary,
That would be a good use. However, some Nepenthes only grow
their "short shoots" vines up some a then abort them in favor
new, stronger, basal rosettes or short shoots which may become
"long shoots". ;) Anyway, I suppose on a very well established
plant, this may be useful. I don't think anyone has yet been
able to get as far as having the two types of flowers on one
plant, mainly for the reason I mentioned above or other problems...
