I am perplexed at this...the species I. versicolor is native to
Zone 3 (here) where the temps. plummet to -40 degrees F each winter.
They are very cold hardy...mulching in the wild here and no pots. :)
Granted, I. versicolor is native to parts of the continent where the
temps are milder...the hybrids seem to do as well as the species.
They also like moist areas but they do not grow in ponds in the
wild here. They are found mostly in sunny, moist areas near a wood.
I have personally never seen them growing in a pond.
