temperate Drosera rotundifolia, intermedia, longifolia, filiformis,....(need cold winter dormancy, frost resistent)
subtropical Drosera capensis, aliciae, spatulata, venusta, slakii,.... (should have a cool winter dormancy, but can be grown year around)
The easiest Drosera
"winter growing Drosera" pauciflora, cistiflora, ... should have an almost(!) dry summer dormancy
difficult !
Queensland Drosera prolifera, adelae, schizandra grow year around under high humidity
most petiolaris Drosera can be grown year around (paradoxa) but some need a dry winter dormancy (falconeri)
raelly difficult !
other "tropical" drosera like neocaledonica, madagascariensis, burmanii, indica .... can be grown year around or are annual
difficult !
Drosera regia can be treatetd like subtropical Drosera but shouldn't be kept to wet during winter
Tuberous Drosera need a dry summer dormancy (at least auriculata can be grown wet year around, but will die back, too)
only a few of them are relativly easy (auriculata, peltata, menziesii,...)
Some of the Pygmae Drosera need a dry summer dormancy, but most of the plants in cultivation don't need it. Some are annual. winter growers.
