I think sundew is more possible to cross if they come from same section.
D. binata,
D. capensis and
D. adelae come from different section. I don't think they can be hybrided. See this site.

I try to cross
D. lanata with
D. ordensis early of this year. Both sundew come from section
Lasiocephala. Here is the result.
