I'm mixing things up a bit with a new Friday* series, fruitful, a series of photographs I've taken of fruit that complement two of my other series: a floral tribute and the fungus among us.
These berries are on the Pyracantha plant, commonly known as firethorn, and I photographed them overhanging the back fence of a home that backed onto Pondwicks Meadow in Amersham Old Town.
According to Wikipedia, the English have used firethorn to cover unsightly walls since the late 18th century.
Its thorns also make it an attractive and organic form of home security.
