Here is the previous inhabitant, a Louisiana iris, which flowered beautifully in early Spring, but since then its leaves have yellowed. I think it needs a good feed, but I don't think that would be so good for the little white cloud fish that live in there. So, I have decided to rest the iris out in the real world for a while and return it before next Spring. Hopefully, once divided and potted into a smaller pot, it will happily cohabit and physically fit in with the waterlily.
Or else I could get another pot to turn into a water feature and have both - I rather fancy the thought of having proper goldfish.
or I could go even bigger, with lots more fish!!!
But I don't really have to think about it till Spring. In the meantime, I am going to enjoy my new addition, and I'm sure the fish will be happy to have the shade and coverage of the lily pads to keep them safe from kingfishers.
