A lot of the ditches in the Jackson, Mississippi area have lost the variety of aquarium plants they used to have because they have been taken over by either a Polygonum species or Alternanthera philoxeroides Alligator weed. We have had several years with below normal rainfall which may have contributed to the loss of other species, or the species that used to be there (Ludwigia, Micranthemum etc.) are pioneer species that get replaced in a process of succession. So, I was glad to run across a new ditch that was created about a year and a half ago that has already acquired an interesting variety of plants. It was created when a bicycle path was put in last fall and the path blocked water flow from a woods creating standing water about 6 inches deep along the path. Ludwigia palustris showed up early this spring and grew with astonishing rapidity. At first I thought that Ludwigia was the only plant, but closer examination showed a number of other species. had also made it there in only one season. I found Ludwigia glandulosa, Bacopa routundifolia, Lindernia dubia, an Ammannia species, Ditch stonecrop (Penthorum sedoides), a possible Mimulus species and some Polygonium. Photos, below show all but the Polygonum.















This photo shows the extensive growth of Ludwigia repens. There is a Ludwigia glandulosa plant in the lower right corner that I did not recognize when I took the picture.

What a great find and nice pictures.

Very nice. So cool! I'll be exploring some lakes and ponds in the Sierra foothills soon for some aquatic plants. Will share some photos then too.

What a find! As I look at your pxs. it occurs to me that I would not even know what I am looking at. I only recognize the immersed versions of the plants. The emmersed versions can look so different.

I find it very useful to stand at the edge of the water and look over the plants with binoculars. Most binoculars made these days can focus as close as five or six feet. I never would have seen the Bacopa or the Lindernia if I hadn't had binoculars.

The Ditch Stonecrop can be grown submersed. See this thread :http://www.aquaticplantcentral.com/f...native-id.html

Very cool. Thanks for sharing man. Have you tried the Ammannia species or the Bacopa rotundifolia submersed yet?

Very cool Paul. Have you determined whether the Ammania is A. coccinea or A. ariculata? I had one of them once, but it got smothered among the other weeds. They are worth a shot in any case.

Some of the L. dubia was growing submersed? We found some of it growing that way up here. It's a very nice plant.

The Penthrorum will grow as a somewhat small creeping foreground stem if it gets a lot of light. With less, it grows larger and taller.

I'd try the Bacopa rotundifolia submersed for sure.

Thanks for the great pictures and thanks even more for labeling the plants. Great job.

Cavan Allen

Do you still have any of those plants Paul? I think the Bacopa in particular is interesting.
