I'm from SE Michigan. I just created a bog garden last June, and it has been a real success so far! Last year, I added Sarracenia purpurea, Dionaea muscipula and Drosera rotundifolia. They all did very well. You can see construction pictures here: http://jeffsgarden.freehostingnow.co...tBogGarden.htm
I am now looking to add other plants, like Sarracenia leucophylla, S. flava, S. oreophila, S. alata, S. minor, S. psittacina, S. rubra, Drosera filiformis, D. intermedia, D. anglica, D. linearis, Pinguicula vulgaris and P. grandiflora.
If anyone has any small off-shoots of any of these, please contact me!
