Lambs lettuce or Mache

I am going to give this a bash over the winter months. My wife has been buying ready made bags of salad and this is one of the constituents. Is it easy to grow?

Good I should be able to grow some then. I am not really worried about the timing of my sowings because we have very different conditions to those back in the slightly cooler UK. I am going to get some rocket going to mix with this mache  and a little ordinary lettuce should be as good  or should I say better than the stuff my wife is buying!
