Corn salad lettuce - useful during "the hungry gap"

Here is one of my corn salad lettuce, also known as lamb's lettuce. Grows over winter so is very good this time of year when there is not much else in the ground. Interestingly, the best crop came from an area where I had thrown some of the weaker seedlings whilst thinning out. They somehow grew and survived the slugs far better than the area of soil with the original row!
