This is a 29 high gallon tank with some plants collected in the Jackson, Mississippi area. In front are a couple of Ludwigia palustris plants, to the right are some E. cordifolius, one of them producing floating leaves. The really big plants behind the Ludwigia are a local Sagittaria, possibly S. platyphylla. I collected them 24 days ago and they are just getting bigger and bigger. So far, they have only produced submersed leaves, but they may start producing emersed leaves with petioles and oval blades which I have seen on some plants in the field. So far, there have been no runners produced.



This is a picture of the Sag. where I collected it.

how does one differentiate between L. Palustris and L. Repens?

HeyPK

Jeez----I can't get anybody interested in the monster sag!

It isn't easy to tell L. palustris from L. repens. Leaf shape is very similar. The L. repens flower has small petals, whereas the L. palustris flower has no petals. The fruit (capsule) of L. repens is longer and sometimes larger than the capsule of L. palustris. I picked up a Ludwigia in the San Marcos river that had large fruit capsules and which I am pretty sure is L. repens. Right now it is growing shaded over by other plants, but I hope to get it growing with L. palustris to see if I can see any differences in submersed growth.

huh... I have been collecting a ludwigia here in northern indiana for a while now and I thought I had it identified as l. repens. Do you know if it even ranges this far north?

That is a really cool sag though!

I does not (not in the central US anyway). You probably have L. palustris.

Sagittaria looks good. But kinda big!

HeyPK

Thanks for the comments on the Sag!

L. repens is well represented in Texas and even up into Oklahoma, but it has not been reported in Mississippi. Along the East coast, there are records up through North Carolina, and then one isolated record in New Jersey. L. palustris is well represented in Indiana, Michigan and Wisconsin. There aren't too many records of it in Illinois, probably because there is almost nothing but corn there.

that sag is pretty cool, where is that pic from a river/ creek/ stream bed or a lake/ pond.

If it doesn't keep getting bigger, perhaps it could be a good alternative to Crinum thainum.

It has a unique look. I think there are some garden plants that look kind of like it. I wonder if it has any value for aquascaping. Maybe not, it makes a big tank look little. I think most aquascapers these days want plants that make a little tank look big.
