Our neighbours have a tree in their garden which at this time of year produces clouds of fluffy seeds which collect in great drifts in undisturbed corners of the garden and greenhouse, and indeed in the house if the weather is good enough to have the back door open. This year it has been more than usually productive. The greenhouse, in particular, looks like it's been filled with cotton wool and I have spent a lot more time than I'd have liked chasing fluff round the living-room with the hoover.
Add to this the remarkable number of dandelions that the warm weather has brought out and it's difficult to go anywhere at the moment without coming back covered in fluff.
It also takes an inordinately long time to get anywhere if you have a dedicated dandelion-clock aficionado in tow!
