I grow baby tears in South Australia and I love the look they give as a ground cover. I always get comments on how nice they look and they give the area a fresh cool feeling.
I got some Lindernia mixed in with some Pond Penny once. The look very similar, but Lindernia grows much faster, and has smaller more ovate leaves with 3 distinct veins. If you want the look of Lindernia, but don't want to prune weekly, try the Pond Penny. Tommy
My Lindernia seems to be prone to either staghorn or hair algae, looks like black hair around the edges of leaves that are closest to the substrate. Tried increasing co2 and then put some in a lower light tank, we'll see.
