If I planted something now, I think it would fare considerably better. With the exception, of course, of plants that do not appreciate the pH and mineral levels associated with the clay.

There are some real differences in plant growth in tanks where the clay can really drain.Here are a couple of pictures from one of my clay tanks.. The bromeliad was rooted directly into the clay (red art/bentonite mix with a thin layer of red art/bentonite/peat). The shot of the roots are those that the bromeliad has grown through an inch of clay, a half inch air gap and into the water.
