Spring has come to our south London streets. The daffs are out, and in our road a magnolia is coming into bloom, its waxy, blush-pink petals bursting out of their downy carapaces which litter the pavement below. There are grape hyacinths in the churchyard, and creeping violets in shady corners. The bees are busy, weeds are germinating and the first of the cherry trees are in bloom. I love this time of year.
