Does anyone keep any tuberous sundews? I am doing some reading on them. It sounds like they are a bit more advanced so not for me just yet, but man. They are fascinating. I have a fantasy of an evil trellis covered in climbing Sundew vines (in this fantasy i also live somewhere with a trellis.)
I realize that this is quite a bit of a late reply, but I had a handful of D. auriculata going for a while. They even started to grow stems (these start out as little rosettes when young). I find them tricky because, if I'm remembering correctly, many of them are Australian winter-growers. So they prefer cooler wetter temps to grow in and the winters here are just too cold. Once you get them germinated and going though, I don't think they're hard to keep alive as long as you keep them stable and give them deep pots. I had mine outside and left them be for too long, so I ultimately lost them to the cold, but I ordered some D. stolonifera seeds recently. So I'm hoping to get some going again.
Did you ever get your hands on any? They are pretty neat! I feel like Drosera species are exotic enough, but these guys take it to the next level.
