It may not be immedicately obvious, but this is lettuce! Red oak leaf lettuce - one of my very favourites - that went to bolt a while back, producing tiny little florets on the top.
I am super wiped today, after a bad sleep, but luckily today is my day off from appointments and such (two more to go this week, it's been a busy one...). That's assuming my poor gums calm down yet, still sore from the brutal dental hygienist and salt swishing like a madwoman!
I'm happy to have some grey weather for a few days after this long hot summer. It suits me just fine.
