Welcome to the forums Laura! I`d say Dino covered it well. But you could also get some hybrid sarrs with cold hardy parents like S.jonesii,S.purpurea ssp.purpurea,S.oreophilla. Also temperate forms of D.intermedia would do well.
S.oreophilla and S.jonesii are very hard to aquire (legally) as they must be given to you free of charge for them to be legal as they are on cites apendix#1. I do also agree with Caps. Plant flytraps! I`d recomend: "green dragon",'akai ryu',"blood red traps",'dentate traps','red pirahna',and of course the typical vfts Id use the typicals as fillers and the others as focal point type things.
