YnghylchAlthough not widespread, where common box does occur, it can often be in large numbers and can live for several hundred years. Found in southern England, Box Hill in Surrey is probably the best-known population in the UK. It thrives on hillsides, and in woodlands and scrub; cultivated forms are used as ornamental and hedging plants in gardens, are often clipped into impressive examples of topiary.
In April and May, both the female and male flowers can be seen on the same plant. Pollinated by the wind, each female flower dries, becoming a green capsule and then, finally, a brown, woody seed case. Common box is popular with bees and provides a dense, sheltered habitat for small birds, mammals and insects.
