Lego's Emersed Growth Experiments

So last summer, I grew a few aquatic plants outdoors in full sun and they did excellent. Now I have the itch to try more species for next year, and I'll try to document my progress here. I am currently acclimating the plants I have to emersed life and I'll eventually harden them off of high humidity so I can move them outside when the weather warms up again.
Current species list:
-Gratiola aurea
-Gratiola brevifolia
-Ludwigia peploides
-Ludwigia senegalensis
-Staurogyne repens
-Staurogyne sp. "Bihar"

I have quite a few more species pending, but I'm waiting until after the holidays to have them shipped to me, this way they don't get held up any longer than they should be.
If you have any uncommon or rare species you'd like to share with me, let me know.

Very nice! Any luck getting fruit on the Lindernia?
Have you tried any Syngonanthus?

So far, I'm 1 for 5 with the Eriocaulaceae family. That Tonina is the only one I've been able to successfully convert to emersed life. I've tried 3 Syngonanthus and Eriocaulaceae Type 2, and none of them did much of anything before finally dying off.

Gratiola brevefolia


Limnophila rugosa
And no, the plants aren't actually fuzzy. The neighborhood Cottonwoods are going crazy right now and sticking to everything.

A few more from my emersed experiments




Polygonum "Kawagoneaum"
Gratiola brevefolia
Cardamine lyrata
Nesaea triflora

How about satisfying us by not posting these spams?
Lego, some seriously nice stuff you got there. Your photography is outstanding, and your plants are pretty amazing too. All those flowers are beautiful!

Ok time for a big update. I've been on a planted tank hiatus lately, but my emersed grow-out project is still going strong. I've only lost a couple species overall, and the rest are doing absolutely phenomenal. Things are growing and flowering much better than I expected, and I am very pleased with how some of these are doing.









Gratiola brevefolia
Gratiola aurea
Lindernia "India" - these flowers are so tiny I can't get a decent shot of them
Limnophila "Sulawesi"
Hygrophila "Araguaia"
Ludwigia "Red" - originally from Manini
Nesaea triflora
Bacopa "Colorata"

Well done! You're growing some great plants, and the photos are beautiful. I image we'll be seeing some of them in the PF soon.

In return for some specimens, I will send you some Gratiola viscidula. I'm almost certain the Lindernia is L. rotundifolia. Any fruit yet? The Bacopa should be relatively easy to ID. Does it have an odor like B. caroliniana at all?
P.S. It's G. brevifolia.

Thanks Cavan! I have a few of the Lindernia pressed for you already. I'm going to make specimens out of a few others for you if you want them (L. "Sulawesi", H. "Araguaia", L. "Red") and send them all at once. The Lindernia's flowers are maybe 4mm across. So small my macro lens can't take a decent picture without a very wide aperture. But it does flower prolifically.
About the Bacopa, I haven't grown B. caroliniana for years, so I honestly can't compare the odor. It does have a citrus-like scent that most Bacopa have though. By the way, any clues on the real identity of B. "Japan"? I have a pot full of it, but no flowers yet. I'll be happy to send a few stems your way if you'd like to experiment with it.
I should have a few species of Polygonum with flowers for you as well. Both P. "Kawagoneum" and "Sao Paulo" are flowering profusely right now.

The 'Japan' could be B. innominata, but that's only a guess (with the possible execption of B. monnieri, there are no Bacopa there). If the corolla is white, that could be telling. I collected some of that species to cultivate and compare, but unfortunately, it melted.
Thanks for making the specimens. Getting fruit for them really helps.
I wonder if the 'Colorata' is really B. caroliniana. Could be. Again, it shouldn't be that hard to ID. The Hygrophila though...a tough one. Very tough.

This is the sound of me being jealous. I'm sure you can hear it halfway across the country. Your emersed collection is gorgeous, lego, and the photos are even more so!
I know how tiny those Lindernia sp. 'India' flowers are! I took one look at mine and said, "forget it!" My camera's not that good. On the other hand, if you're looking for a Lindernia with gorgeous and big-enough-to-see blooms, try L. grandiflora. I've got a small specimen of it, the flowers are a rich, dark purple with white accents and, as the name implies, somewhat larger than the other Lindernia species I've had a chance to flower.
As for the Ludwigia sp. 'Red' - am I mistaken, or isn't the petal-less flower usually indicative of L. palustris?
