I guess some of my lettuce decided that frame provided enough warm air and started growing. Not much of it of course but then it wasn't exactly seeded to grow - it's a leftover from summer. And on another side of the same box I found some bok choy - also left overs. They're not in great shape but pull back old leafs and you'll get a few good shoots for stirfry.
And in another frame self-seeded parsley woke up! I mean self-seeded because there was a parsley patch before that I picked and dried for winter but I guess some seeds spread anyway so they started growing and one of the older plants came back to life as well. Unexpected but always welcome as I use alot of parsley in cooking.
Actually I'm surprised that anything grew at all since the coldframe was closed and I didn't bother watering or doing anything else and grown was bone dry. And yet these little buggers still made it through most of the winter. I guess you can call it first harvest of the year :)
