This thing has leaves that float and take the shape of a flower, which I think is pretty nifty. It grows on long brown stems that I'm 85% sure are rooted into dirt. Any idea what it is?



It seems to have taken over about 1/5 or so of a 6 acre pond. You can see here what it looks like on a large scale..



Sorry, that's the best picture I have. I realized there were leeches in the water I was standing in, screamed, and ran away. I can go back tomorrow and get better pictures if need be.

Ludwigia peploides perhaps? It will usually root under water and then the tip will float on the surface. It hates being completely under water, so if you try to submerge it, it grows several inches per day until it hits the surface again!

Wow, that's pretty impressive!
I don't know if it could be Ludwigia Peploides, google shows it having yellow flowers. I've never seen this plant flower, but then again I may just not be remembering. I go to this pond for photoshoots so until recently I have only seen the plants there as background, not something to look at more closely!

Ha ha ha ha ha !!!!
I just spat my afternoon coffee out.....thank you :)
I stole it as my signature ;-) Now ill remember why i have a coffee stain on my white shirt !

And I thought crabs n scorpions are the only scary things in fresh water lakes n ponds. :eek:
looks a lot like peploides to me as well. nice find!

Noppee. There's also big crayfish in there. And the leeches are really small so it's scary not knowing if you got them all!! I spent about 10 minutes checking over my legs and feet to make sure I got them all off!

To the OP: ever read "Stand By Me"?
No I haven't, why?
You should read it or watch the movie, the leech scene is classic

So I went back today and got some more pictures. Here's another huge patch of the stuff, on the other side of the pond. And the egret, once again, is photobombing my pictures!


You can see that it gets taller as it gets closer to the shore

Here's a small piece I uprooted(shame on me)


And a large piece I pulled up, but didn't uproot...The very bottom is rooted, but none of the small bunches of roots were. I'll just link to this picture since it's super tall...I don't want to stretch out the page

It turns out I did find a couple of these flowers. Only a couple of them though...It's probably just not flowering season, I guess.



So you guys think it's ludwigia peploides? Can these be kept in aquariums?

Most definitely Ludwigia peploides. Thanks for sharing those awesome pics!

Probably with some gourami or betta(might reduce dissolved oxygen levels), no high light submerged plants, and a some above tank air circulation, might be good nitrate reducer also. I have not gotten any of my plants to bloom despite my best efforts and trolling around these forums

Are these in Florida or North Carolina?
You could definitely keep it in the aquarium. It would be a cool floater, but not good for underwater use. I say go for it!

Eh, not really. Not other Ludwigias anyway. It basically functions as a rooted floater. You can grow it submerged if you find a small one, but it really just wants to make it above water. Anything that grows below water will regrow if clipped but won't branch. It would dominate the tank if it did reach the surface.

<--- Check my location (; California. Northern.

One more question, from the plant newbie here...what is this? This is growing in huge quantities in the pond, too. Sorry, bad pictures.

Probably Myriophyllum spicatum, a noxious weed.
Probably Myriophyllum spicatum, a noxious weed.

If it was noxious, wouldn't it have killed all critters/fish in the pond?

It could. Noxious doesn't mean poisonous if that is what you are thinking. It refers to non native invasive plants.
How it would kill by crowding out living space used by native plants and in turn as food for the little critters that call the pond home.
