I'm in Georgia Zone 8 and lost mine, over the winter. String algae
coated it and I suppose that was a factor, but I really don't know why
it died. Parrot feather and anacharis grew well in spite of the
string algae. I don't plan on replacing mine, I'll just move on to
another plant until I get one that winters well.

Regards,

Hal
