Well I opened my package today from Black Jungle terrarium supply with great expectations and what I see in this 2 1/2" pot before me is most likely U. longifolia and not U. alpina. Doesn't alpina have kinky sided leaves which stand almost errect? these are basically flimsy 2" long and flat but do come to a sort of petiole near the soil.
Anyone have photos of young alpina plants they could show me to compare to before I send a complaint to BJ? (the pics on their site catalog does looks like alpina but this doesn't).
