Lettuce flower

I'm blipped this lettuce that seeded itself in a crack on the patio a few weeks ago. I have left it there to grow and go to seed to see if it would complete its life-cycle. I noticed now that it has a flower so it is still going strong. This morning I did some admin and also went up to the Catholic church to examine the radient heating system they use. I prepared two loaves, did some work in the garden and in the afternoon went down for my physio.
