I can get it but it is sometimes a difficult plant. It has sensitive roots so when you plant it, all the 4 leaf sections fall off until you are left with the roots where it will grow back starting from a 1 leaf, to 2 leaf, and so on which will take some time.
You can get it online at some of the places that sell plants. I got some and it was like $4 or $5 for a potted plant.
I got 3 pots and it is doing really well in my tank.
But it doesn't keep it's 4 leaves, but still pretty, at least I think so
Never kept it and I'm just a dummy that knows nothing about plants- but if memory recalls: I think you can keep the 4-leaf form if it is floating or emersed- but it grows as a 1-leaf form is when it is submerged under low to moderate high light.
