I have had this plant outside unprotected for 5 years, They need occasional thinning byt uprooting the clump in late winter, early spring and dividing the corms. Will not grow during cold weather, but once it warms over 50 degrees it takes off. You cannot overwater this plant and do not allow it to dry as the growing will stop.

Has done great indoors, constant moist soil with some (very light) direct sun in the early morning. Otherwise just very bright room. It's by a window so gets some breeze to keep it cool. Not colder than about 67F. Constant new growth but isn't getting much taller than 3.5-4 ft tall. Perfect indoor plant. Some occasional misting keeps it happy.
We had an awful, cold winter in Oregon last year...I had this plant in a pot with no protection and it got the full dose of freezing snow and ice (low 20's at least). The main tuber died out but I have babies coming up now in August! Under the right conditions, this is hardier than listed. I also have one as a houseplant that looks great and is evergreen indoors with low light levels. Do NOT use it around pets or kids that might bite the leaves!! The oxcalic crystals cause a terrible abd prolonged burning sensation in the mouth.
