    I was curious about emersed growth so I setup a 55 gallon aquarium outside with potting soil and lots of water. I also covered the aquarium in plastic wrap to make a green house. Half the aquarium was devoted to hygrophillia difformis and the other half to some hot pepper seeds.

    The hygro promptly died back in a few days whiile the peppers sprouted nicely. Being lazy/patient I left the hygo in there for 2-3 weeks before checking again. When I got back from vacation today I noted that EVERY SINGLE stem of hygro. was sending up new growth. The physiology is quite different looking, right down to what looks like small hairs on the stems (unless this is a fungus/mold growing on them). I'll have to take some photos of a side by side comparison and post them at some point if anyone wants to see...

    I did not fill the greenhouse with water. Just made it very moist... just short of muddy.

    I think I will try putting a leaf from a bananna plant next and see what happens.

    Cheers!

    hi

    the shape of the leef depend of the humidity.

    1~ 90% to 4~ 60%

    Sounds interesting. I'd be interested in some photo's. When I was little I remember my dad planting all kinds of "odd" things in his little hot bed he built. He was always just trying things out to see what he could grow. (I'm trying to get him into starting a planted tank.)

    I was looking on the internet at some aquatic four leaf clover plant last week. Then I got thinking about this lighter colored clover I see growing here. (Yellow woodsorrel) I picked a little bunch and washed off the roots and stuck it in my tank. It's doing fine so far, but I suppose it'll die. Maybe I'll be lucky and be as successful at growing it in my tank as well as I can grow weeds in my yard. LOL

    Most aquatic plants possess emergent/submersed heterophylly.

    In those pictures, you also may want to measure light as well, I know that shading/intensity will also play a large role.

    Here is a general view of the other ones popping up in the greenhouse. The soil is potting soil with a lot of water, making it muddy.

    Thought I would post a more recent photo... Lots more growth in the green house now. I added some more tops from trimmings. Not really sure what I am going to do with all these plants.
