thorn hedge

To sit in the sun and read Columella on how to plant a thorn hedge is a pleasure I had to teach myself. No, I was teaching myself something else, and the thorn hedge came, wisely, to take its place. They're longer lasting than stone walls and have an ecology all their own. Birds nest in them and snails use them for a world. Hedgehogs, rabbits, snakes, spiders. Brier rose, dog thorn. There are some in England still standing from Roman times.
