I. lacustris is a tough plant. Local average temperatures range from
about a high of 25ÂC in summer to -15ÂC in winter, with extremes to
40Â and -35Â. Snow cover can be heavy to negligible. They often grow
right at the edge of the forest on rocky beaches, directly exposed to
sun and wind for at least half a day. Frequently the rhizomes are
fully exposed except for the rooted tips.
This species actually grows better for me than most I. cristata, which
I've killed several clones of.
