Have you ever encountered Ludwigia polycarpa? I'm eager to find that one.
It seems that many of these plants that do well in low nutrient conditions don't fare so well in many aquariums, which is a real shame. Gratiola aurea is a fascinating plant (supposedly grows in water up to 14ft deep!) but only seems to really thrive in mineralized soil tanks. Juncus pelocarpus will grow, but at an absolutely glacial pace. M. tenellum is fairly similar, though I'd like to try it from a different location that where we found it last. Elatine minima seems to always eventually rot from the bottom up, though I think that if you could keep it going long enough, you might be able to get some of it 'over the hump'.
Eriocaulon aquaticum differs drastically in terms of suitability from one location to the next; some stay pale and small while others are robust. That gives me hope for some of the others.
