There are two types of water lilies ... Hardy safe to low freezing temp.
(under the water) and Tropical ... will not survive water temps below
450 for a protracted length of time.
They will both lose the floating leaves (pads) but the hardy will send
more pads to the surface when the temps get around 500. Best thing to
do with the tropical is remove the tubers and store in damp peat moss
over winter. Worked for me down here in New Orleans.
Water Hyacinth , if it freezes it is toast ....
I have never had much survive freezing even down here. this is probably
the only reason it doesn't choke all of the water ways down here. Mine
have all turned to sludge after freezing.
Stay well,
Leo
