Update, finally.
I ended up changing out the slate for some larger rocks. I know it was sort of popular, but it really cut back on the area that could be planted..and more to the point, it was soooo low, that I think it would have been pretty much lost in the growth, even the foreground growth, anyway. Also....I found some REALLY cool rocks at a local quarry....
Anyway, in sticking with the local aspect, I decided to try to use ONLY local,
"free range" plants.
This early in the year, just finding emerged aquatic plants has proven a challenge, and so far I've only been able to find a handful of species. To get the tanks started, I put in some higher stem plants; Myriophyllum elatinoides(I "think" we call it foxtail), and Elodea canadensis(anarchis..sp?)....those being what I could find so far, as far as stem plants go) around the rocks and logs, and laid in a foreground carpet of dwarf hair grass(found a GREAT source for that in a local lake!), and what appears to be some kind of extraordinarily tiny Val or Sagitaria-like plant...I mean tiny! It has flat, long leaves, and is strung out along runners. It was growing in about 2 feet of water, and the lake is at normal levels..so it's definitely an aquatic. I really hope it takes off, as it's pretty cool looking...in the lake, it was growing in a very large mat.
I also tossed in a lone example of a Potamogeton(exact species, not sure..and it's pretty sickly looking anyway!), and a threesome of some kind of lilly-esque thing..NO clue..but it was growing quite deep...
Note..I will be adding more plants as they come up..I want to add some more Potamogeton of some kind(we have a few types here..but I've not yet collected any more),some Ludwigia, and anything else that catches my eye.
What I seem to be strugling with...is finding a local mid-layer type plant. So far...I have used the rocks to sort of ease from the stems to the low cover plants, but really would like to find something of mid-height. Perhaps when it warms up a bit, I can find more...
Anyway, here are some pics from today, after the planting, and after the water had time to settle a bit.
Sucky pics of the mystery sag-like plant..:

Some of the hairgrass...the area I found it, was literally like a carpet!
