The Antirrhinum (below), commonly known as the snapdragon has been a popular garden plant for many years. Also known as the dragon flower, its common name derives from the resemblance of the flower to a dragon’s head.

When laterally squeezed the dragon will open and close it mouth: ask any grandparent whose flowers have been decimated by over keen but clumsy grandchildren. Yet once the flower has died, leaving behind the seed pod, something a little more macabre appears. The dragon – just a visual metaphor after all – appears to have a skull.

Little wonder, then, that ancient cultures held the snapdragon to possess supernatural powers. They were thought to offer protection from deceit, curses and witchcraft if they were planted in your garden. Another myth maintains that they are able to restore youthfulness and beauty to any woman who ate them. It’s a wonder that the witches didn’t raid the gardens in which they grew to repair their own ravaged features.

Yet in these enlightened times the majority of people do not believe in witchcraft and sorcery – not to mention dragons. However, when presented with the seed pod of the snapdragon, the skulls of so many dragons, one might be forgiven a moment’s reconsideration...
