Hi Fernando,
I don't have anywhere the experience with Drosera that you or Jan do
but I'd like add a bit in here for two plants I am familiar with.

Ok, D.brevifolia is not an annaul! Everyone has told me so yet
my plants are now two years old. Not a one has died and yes I
allowed them to flower a set seed this year. They survive the
drier seasons by giving up their rosettes and only the roots
remain. Perhaps a bit of the stem lives too but this isn't
needed for the plants' survival as I have had no trouble producing
numerous rosettes from root cuttings. Infact, these plants remind
me of D.hamiltonii since their roots are so much larger than
what it seems the rosettes should need.

Yes, there are many forms of this plant. Very resently, I began
to think of D.capillaris as N. America's D.spatulata.
Thanks for bringing this to the list.
