You just cut off the flower? How mature should the flower be first?
Echoing nimbulan, the majority of drosera are perennial. If you don't want to keep them indoors, there are many temperate species that you can stick outside for the winter, such as d. filiformis. Never be closed minded with the abilities of sundews, they live all over the world and are one of the most diverse carnivorous plant groups.From the little bit I've read it sounds like drosera are annual plants- so can I grow them for longer than one season as long as I get an indoor setup or what?
