Not a dandelion

Today I biked to and from work. The day was glorious and in the evening after the exercise my blood pressure was nice and low. Work was mostly taken up with a 4 hour training session on MuleSoft, we're nearing the end of a 8 week training course (one day per week). It's rather good but sometimes it's hard to see what is going on, and the level of the sound on the videos varies a bit.

Today's (back)-blip is a clock of a catsear (Hypochaeris radicata). It is not a dandelion but a relative. apparently you can eat it, but I don't think I'll bother. It's growing in our wildflower lawn, where it is supposed to be, unless we get too many of them.
