D.rotundifolia would do well for you, too, it is the toughest one I have growm so far, and as the others mentioned, D.filiformis does really well for me outside (and I leave it out year round, mulching with pine needles for winter)
You can grow lots of stuff outdoors if you bring it inside for winter- I have some D.capensis that I started from seed in March or so, the ones inside are doing well but I moved a couple outside and they are MONSTERS compared to the indoor ones, and I also have D.tokaiensis outside and it is doing really well (I am going to try and leave a clump of them outdoors to see if they will go dormant since they're a mix of pretty tough sundews, we shall see)
