You don't have to ask the people that live there. We can somewhat answer that question for you. With heavy mulching, you can grow vft's, almost any Sarracenia, D.capillaris, and maybe Darlingtonia california.
With light mulching you can grow D.rotundfolia, intermedia, linearis, anglica.
When you mulch use only pine straw, nothing else.
I don't grow butterworts but I think you can grow P.vulgaris, macroceras, and villosa. The best thing for you to do is experiment with a few plants, so that you can fine tune the way you grow them to fit the climate where you live. I think it's possiable for you to have success with all the plants I listed. If you have any questions feel free to contact me.
