The tuerckheimii has been such a surprise. I thought it on death's door for months - no roots, growth... nothing. I reluctantly super glued it to a (largish) flake of moss covered wood and put it in my terrarium (not really where I wanted it) and away it went! Now it's growing everything and quickly. It's a great plant, IMO!
I haven't had the floribunda very long, but many places say the tuerckheimii is a subspecies of floribunda. Andy sells them, though his look different than mine- I get the feeling floribunda has a lot of variation. It has been pretty easy for me- hasn't died in 3+ months even without roots. I keep it in intermediate temps. 60-64 at night and 70-75 during the day.
