Botanical lore

guelder roseA deciduous, spreading, asymmetrical shaped shrub, growing to fifteen feet tall, peith/ guelder rose is also known as walter-elder and whitten. Other names for this shrub include cramp bark and snowball tree and all are species of viburnum and native to Europe and Asia. Excellent in damp soil, scrubland and thriving on limestone, guelder rose prefers to grow at low altitudes and in semi-shade. Its three to five lobed leaves grow opposite one another, being two to four inches long and broad, with a rounded base and jagged outer edge. Looking somewhat similar to a maple leaf, guelder rose leaves can be distinguished by their slightly wrinkled surface.

guelder rose Growing from the top of the stems, its flat, cream/white, 'lace-cap' flowerheads appear in May or June and are visited by many insects including hoverflies. Guelder rose has white hermaphrodite flowers, produced in corymbs (multiple flowerheads) of up to four and a half inches diameter. Each corymb comprises a ring of outer sterile flowers that are one and a half inches diameter with conspicuous petals, surrounding a center of much smaller fertile flowers, that are pollinated by insects.

guelder rose The fruit is a globose bright red drupe just over three inches diameter, each containing a single seed. Although dispersed by birds, these large clusters of round, brilliant glossy red fruits are almost translucent, and remain on the plant throughout the winter. Beetles will feed on it throughout adult and larval stages. Eaten raw, the fruit is edible in small quantities, yet has a very acidic taste that can be mildly toxic, causing vomiting. It can however be made into a jelly or even a cranberry substitute, or as a preserve.

guelder roseMedicinally, the guelder rose has extensive uses, since both leaves and fruits are anti scorbutic, emetic and laxative, while its bark contains 'scopolamine', that can sedate the uterus when used dried in a tincture, known as "Cramp Bark", to alleviate painful menstrual cramps. Its homoeopathic remedy is made from the fresh bark, for a cardiac tonic and cardiovascular muscle relaxant.

guelder roseAlso used, sometimes as a tea, for a herbal medicine to treat cramps, swollen glands and asthma, guelder rose is anti-spasmodic, and good for colic, constipation, irritable bowel syndrome, as well as the physical symptoms of nervous tension, spasms and debility. A red dye is obtained from the fruit and can be made from the dried berries, while the wood can be used to make skewers.
