Make your own list!
From the ones listed by Tamlin i never had any problems with citrina, grievei, hyperostigma, leucoblasta, microscapa, oreopodion, pycnoblasta, sewelliae and spilos.
Different growing conditions make different results. I'm usually ignoring lists of hard to grow pygmy drosera. This is why some find one species easy and others find it hard to grow. For me i'm more careful with closterostigma and stelliflora. Miniata, eneabba, leucoblasta and androsacea go dormant for me but they come back with no problem when the temps go down.
