You can see how the shrub got its name when you look at these bladder-shaped pods. These were on a very large bladdernut shrub not far from the pond. I am very ashamed to say that even though I walked by this for years, I never really looked at it, and forgot it was there. Yet I planted this in about 1996! It was donated to us by someone whose name I now, unfortunately, forget. I always assumed that the shrub had died because in later years I thought I'd planted much further from the pond.
