I know S. purpurea ssp. purpurea is much harder to take care of than S. purpurea ssp. venosa because it needs a very hard dormancy and most people do not live in such places. I however live in a place where S. purpurea ssp. purpurea grow (I live like 50 miles from a site). Would it be possible to grow it outside all year round? I asked this on CPUK and they said it should, however Barry Rice said probably not, I told him about the CPUK opinions he said 'maybe'. Would D. rotundifolia and D. filiformis var filiformis, Drosera intermedia, (I think thats the northern one) grow fine up here too?
I live in Zone 4. The lowest temps we get are about -30F.
