Is this Red Root Floater?


@taari: that doesn't look like RRF

@firemedic: that definitely isn't RRF

Not Frogbit either. Here's pics of my Frogbit. Notice how the leaves aren't glossy.

That looks like dwarf water lettuce. My frogbit had a thick spongy leaf and was glossy green.

Your plant is Pistia stratiotes, aka water lettuce. There's no dwarf form, just plants that are smaller from being grown indoors.

Check out Spirodela polyrhiza which has the same lines in the leaf, red bottoms and white roots.

I have seen red root floaters with white roots and some with pink, not red, roots. Water nutrients seem to play a role in the root color variation. My guess would be the amount of iron. But I don't know what the optimal conditions are.

As to the leaf color, Christel Kasselmann's book
Aquarium Plants Aquarium Plants
characterized the plant as being "extremely light-hungry".

Actually mine are RRF. This was them when I first got them. There was nothing else mixed in. I know this because I put each one in by hand to make sure there were no other species.

No. They all look like single leaves up to four leaf clovers.

The color of roots and leaves are often influenced by environmental factors like water nutrients and light intensity. They are therefore not very reliable for plant identification. But the anatomical (structural) features of plants are very stable across environments.

Since we know that red root floaters are populated through runners, when there is no runner and yet the plants keep populating themselves, we know that they cannot be red root floaters.

Taari - Not RRF
Firemedic269 - Not RRF
chris.rivera3 - That's RRF
mistahoo - Not frogbit. That's water lettuce
bluestems - I think you nailed what Taari has.

RRF propagates through runners, creating great big chains of RRF, not 4 leaf clusters. New leaves tend to curl up at the sides and overlap existing leaves, and with proper lighting you get little white flowers.

I would have to agree after those pictures.
