Iris grow so outrageously I'm considering not putting them in my ponds
anymore. Their roots spread to nearby pots and they choke out other plants.
I didn't put any iris back in my 800g pond after we cleaned it last summer.
Pickerel weed is the same. I don't use them anymore. I'm going to stick to
more controllable and manageable plants like the arrowheads, mini cattails,
mini papyrus etc.

Iris is one of my main filter plants. I will need to transplant it
every 2 years to manage it. Also, they are very heavy to move. I will
be moving them into many smaller pots. When I sink it on the bottom (2'
deep), the leaves grow up out of the water by early spring.
