According to Claus Christensen (Tropica Denmark) the overall success rate 
with Madagascar lace plants (long term), no matter _what_ you do with them 
is only around 10%.

That's not to say _other_ people shouldn't keep spending the money to figure 
out the secret.<g>

Of course, even starting with different size tanks _slightly_ changes the 
dynamics.  They can't be lit exactly the same, etc.

Check with your state department of wildlife and make sure that collecting 
native plants for private use is allowed.  Also ask them if there is a list 
of endangered/threatened species that you should avoid.

The best book I know for identifying native aquatic plants is "Common Marsh, 
Underwater and Floating Leaved Plants of the United States and Cananda" by 
Neil Hotchkiss, ISBN 0-486-22810-X.

Here on the East Coast, while there _is_ native Hornwort, most of the stuff 
that strangles ponds and lakes is an exotic introduction.

Maybe, but more likely because it's getting to the end of the season. The 
aquatic plants are slowing down dramatically around here too.

Hygrophilas are all tropical. It's unlikely that  you collected that 
locally. (Didn't you say you live in Wisconsin?)

The lawn-like plant is probably either Eleocharis sp. or one of the small, 
continually submerged Sagitarias. (although there are other possibilities as

Remember that as well as water chemistry changes, these plants undergo a 
_dramatic_ change in lighting.  Both factors will slow down growth, even if 
you harvest earlier in the year.  As I said, at this time of year, they are 
already slowing down naturally.
