What Time Is It?

About 300 yards from our Nat's house in Leeds is a play area surrounded by quite a lot of grass. As we drove past on our way to the house yesterday I was stunned by the number of Dandelion clocks that were sticking their heads up.
Strangely enough as we drove from Blackburn along the A59 towards Skipton, I commented on how many yellow heads were showing in the roadside verges. But in this part of Leeds the heads had all gone to seed.
