Many moons ago, I had some type of large hybrid ping that I used to catch fungus gnats around in a mini greenhouse. I cannot remember what it was, though the leaves were large and pale green and the flower was purple. It had no dormancy period.
I presently find myself in a position where I am managing a research greenhouse and would love to incorporate some pings as natural 'pest strips'. Partly for the pests...mostly because I love pings and other carnivorous plants. Do you folks have suggestions as to an appropriate species or hybrid and where to attain them? Thoughts on what type I had in my earlier life?
of course it also depends on what kind of greenhouse you have.
Some Orchid growers use P.moranensis for this purpose, because it is cheap, big and easy to keep. It used to be one of the most common Pinguicula in cultivation. In a small setup (like an indoor mini-greenhouse) a small species like P.ehlersiae/P.esseriana would fit better. Most Pings have a rest period with reduced, non-carnivorous leaves during winter. Then there are of little use as living fly paper. P.emarginata does not rest. Neither does P.gigantea, which would be good, because it is even bigger, has glands on both sides of the leaves and it catches prey all year round (=tropical homophyllous growth). But it is slightly more picky and harder to get hold of.
Another good CP choice would be the easy to grow D.binata (better D.binata var. multifida, best 'extrema'). It can be grown in between or in hanging basquets and sweeps up anything that flies up to the size of house flies and butterflies. But is has a resting period in winter too.
