The watercress will stay green and not be damaged by frost.
It may get darker in color but it will be fine.

Oh good, i will go get some this weekend. I have a tank full of pond plants
in my basement waiting for the correct moment to put them outdoors. Gonna be
in the mid 30's tonight. I got them thru the winter so i dont want to chance
them now outdoors in cold weather. I dont have any for a veggie filter as
yet but i will.
