I have a complete and total newbie question.
I see all kinds of neato crosses between various Sundews, but, I am somewhat new to growing plants, so... I guess my question is, is there a limit as to how far you can cross one?
I am not talking about crossing 2 crosses, I know sundew hybrids are sterile.
What I mean is, would it be possible to cross a tuberous with a cape sundew, for example? Or a D. Filiformis with a Pygmy? Is there a limit as to how far apart two sundews can be before they stop being something you can hybridize?
