Watercress loves moving water, the faster the better. The roots do a great
job filtering and if you get too much you can have some for lunch.


For some reason, people don't mind eatting watercress and waterchestnuts
that have been grown in an unseen pond miles from home, but have a problem
with watercress grown in their own pond...
