Radishes and beetroot are coming up as well. I planted some carrots, harvested some leeks and did loads of hoeing.
I also mulched the rhubarb and raspberries with some well rotted manure.
I have a fondness for my two rhubarb plants. They are the only things that were in the allotment when I took it on a year ago (except mountains of weeds!) and they feel like they are the connection with what has gone on before in that space.
