Well I like Pinguicula primuliflora a lot and have tried 2 or 3 times before.
Growing in different media and locations, but still have it die in the fall.
I've tried keeping it very wet with a soil mix of 50/50 peat/perlite.
I've tried it damp with a soil mix of 50/05 peat/perlite with a top layer of living Sphagnum.
I tried placing it into my garage with all the other temperate plants during winter.
I tried letting it grow on the south facing windowsill over winter.
It always dies on me.
I was at the garden center today and there was a very nice one with several plants on some leaf tips. I could not resist, even every attempt I've tried so far with the plant has failed.
I'm thinking of growing it in a 50/50 peat/sand mix in my terrarium. Not sure what I should do with it in the fall though. I do change the light schedule and temps in the house do cool a little, but not a whole lot.
What are the secrets to growing this one, or other tips you can offer so I might be able to grow it over a years time?
