I have Hydrocotyle verticillata in my yard that I planted in my tank when I was setting it up. I have found it to be a very slow grower and I removed most of it for being covered in algae. Once the tank found balance the remaining patches are fairly clean (with the help from some industrious amano shrimp I'm sure), but they don't seem to be growing much. They are super cute though, like little toadstools. Since they aren't causing me problems, I let them be. Reading about it online, it seems like most people think it needs to be in a high tech tank and can be a little demanding even then and that seems about right to me.
But free plants are fun, right? If you want to try them anyway, I have some advice: dig some up, rinse them as clean as possible in the sink and then submerge it in a glass of tap water. Leave the glass in a spot with indirect sun for a couple weeks and top up the water as needed. Once it grows new submerged growth, plant that in your tank and toss the original emersed material.
I did both the method described above and also planted some newly dug plants directly in my tank and the plants from the glass tap water did a lot better in the long run. They are the only ones I ended up leaving in my tank. I didn't worry about adding ferts or anything to the glass - It was just my typical soft, alkaline, chlorinated city water. The plants had enough stored energy to make the transition without it - they are weeds, after all. I suspect that the lack of algae spores in the glass gave them an advantage to the ones in the tank, but I don't really know.
