Watercress - our new house guest

We had a very sad bag of watercress in the fridge so Mr M popped it into a washing up bowl filled with water to try and revive it.

And look what happened - a little tlc and it has perked up - so much so that some of the stems are now standing out of the water and flowering.  In less than 12 hours. Talk about making yourself at home...

Have you ever tried to grow watercress?
