Last year I put together two small ponds made from 50 gallon tubs. I had irises in one, which had gotten too big for their pot. I divided them and put a couple of them into the other pond.
Now, what I was sure were irises are...not. They've grown about 4 1/2 feet tall with thin, concave leaves. The bases look nothing like the other irises I have. Hopefully, the picture comes along with my text.
Does anyone have an idea what this plant could be? Is it just an iris that went nuts? Just to the right of the mystery plants is an actual iris (I know for sure, because it bloomed) that I've cut back for the winter. (Ignore the cherry tomatoes that have decided to use the plant as a scaffold.)
