Hi Anita & Vicki, I tried growing watercress in a pot standing inside another pot with water in it last year & it kept growing for a few months . I was able to get a few cuttings from it before it went to seed & finally shrivelled up! I just bought a pack from the supermarket & saved a few pieces which I rooted in a glass of water & then planted in compost topped with gravel & put it on the kitchen windowsill where it grew quite happily. I tipped out the water every so often to freshen it up.It was my O.H. who asked me to grow it as he'd seen Jamie Oliver making ham, mustard & watercress sandwiches on T.V.!
