Here is a pretty (though unintended) flower bed on the allotment. The mauve/purple spikes in the middle are Anise Hyssop (Agastache foeniculum). The sea of white flowers are Radishes (Raphinus sativus) that have bolted. I seeded them a couple of months ago then didn't get round to picking them because I was away.

Spot the white butterfly on the white flower!
