I am interested in Drosera pollination. I have several Drosera flowering right now such as capensis, spatulata, spatulata fraser island, spatulata x capensis, venusta, capillares, omissa x pulchella, nitidula x pulchella, and my adelae. Can I pollinate any mix I want for seed? which ones do not cross pollinate? I am interested in mixing venusta x capillares as they both color very nicely in direct sun.
