No doubt these are as exotic and appealing as the far flung Isles of Langerhans.
I wish they were. Elodea is such a pain. You can't eat it (taste's lousy even covered with ketchup or maple syrup), you can't smoke it (it's soggy and hard to lite, even if you do get it to burn it's real harsh tasting and has a fishy after taste) and you can sit pond side and just about see it growing. It will grow in incredibly deep water - not just along the shoreline. Next year I'm gonna chemically treat it.
