Bloody Crane's-bill (photo by Steve Townsend)The vibrant blooms of Bloody Crane’s-bill are better known as a specialty of the limestone cliffs and dunes further north in Britain, and it can be a surprise to visitors to The Lizard to find it here, and on heathland, no less. But, of course, The Lizard is special, and that’s all because of the serpentine rock that underlies a large part of the peninsula. Although serpentine is low in calcium content, it is high in magnesium, another alkaline element, so plants that simply demand a soil composition rich in bases, but don’t need it to be limestone-rich, can thrive. That includes the glorious Bloody Crane’s-bill. (Find out more about how the soils and geology of The Lizard make it so wonderfully rich botanically).

Bloody Crane's-bill fruits (photo by Steve Townsend)You would think its common name refers to the colour of the flowers, but this isn’t so. In fact, it is in reference to the red colour of the leaves in the autumn. Like several other Crane’s-bill species, the reference to the beak of the crane is a nod to the long shape of the fruiting bodies (see photo to left).

Bloody Crane’s-bill is a perennial that grows from rhizomes. The leaves die back in the autumn, and next year’s buds rest just below the ground surface, ready to burst into crimson life the following summer.
