Has anyone tried a calciferous fen garden? I'm giving it a shot with Cypripedium reginae, fringed gentian, and maybe Aconitum uncinatum (if I can find a source for it).
I'm going the high nutient route, but I've also heard of natural low-nutrient alkaline fens with Carnivores, but never heard about anyone trying that, or what companion plants they used. For that matter, I'm not sure how one would duplicate the unusual soil of a low nutrient calciferous fen. Thoughts?
