Can I grow a new plant from this?

[Vincentfong]

I bought some plants from someone a while ago and a piece of what I assume to be cabomba came with it. It has a root but doesn't include any stem so I'm wondering if this can grow into a whole new plant. I know in the case of most terrestrial plants, even if you manage to root a leaf, it will die as there is no stem or buds so please only answer if you know for sure or have successfully grown cabomba from just a tiny bit of leaf before. Also can I just leave it to float? Thanks!

if it is cabomba or some closely related plant, it should survive fine without needing to root it.

however from how im seeing it, it looks pretty small and usually at that size they are still connected to their mother plant.

give it a shot though, if your water flow isnt extremely high, youve got light and nutrients it should grow, ive had little cuttings grow with less
