pennywort as groundcover?

[PrincessPea]

Hey guys,
I have seen recently a photo of a tank with what looked like pennywort (Hydrocotyle sp.) as a groundcover. Anybody know how this is done? it looked like it may be one long runner held under the gravel, or a different ground-hugging type altogether. Whatever, it looked very cool and I would like to see if anyone knows how they did it.
P.P.

I am using (experimenting) with pennywort as ground cover. Looks good so far. I have to keep the end buried. It wants to grow up and out.

There are 2 types of hydrocotyle.

Hydrocotyle leucocephala, which is the most commonly seen in the aqua hobby. This pennywort is more or less used as a floater, though can be treated as a stem plant if one end is clipped with a weight.

The other hydrocotyle is Hydrocotyle vulgaris/Hydrocotyle verticillata. These plants grow completely different from the one above. Each node has a longer stem to it and they grow looking like mushrooms. From these 2 varieties one gets its nodes to about 2" the other to about 4".

The 2nd ones are the ones best used for ground cover since they will actually build a slight root structure which will hold the plant down.

sweet, this H. Verticallia looks like what I was looking at. Now if I can find it!! I was just considering burying the stem of my floating pennywort, but the other looks way easier to manage.
