| | Re: Ludwigia pilosa emerged
I added a photo to the PF of a herbarium specimen with both leaves from a mature emersed plant and with stolon leaves. Note the stolon leaves, which are basically what we see in submersed culture(on the right), are arranged much farther apart than cultivated plants.
Nice stand of pilosa. Care to share cultivation details? I'm growing mine under T5s in my 40 breeder.
There is a closely related species (L. ravenii) that is somewhat smaller and could be really nice too, but it's quite rare (naturally) and might be pretty hard to find.
