Description of Plant(s) and Culture

Hawthorn, a compact, deciduous tree, grows as either a shrub or a tree, to 15 feet; its trunk or stems have hard wood, smooth and ash-gray bark, and thorny branches. The small, shiny leaves are dark green on top, light bluish-green underneath, and have 3 irregularly toothed lobes. The frail white flowers, known as "may", have 5 round petals and grow in terminal corymbs, spreading clusters, during May and June. In some varieties the blossoms may be pink or deep red. The fruit, or haw, is 2-3 seeded, egg-shaped, freshly pome, scarlet on the outside, yellowish and pulpy on the inside. The berries or fruit hang in small bunches from the thorny shrub, each berry has 1-5 seeds. Berries remain on the tree after the leaves fall off in autumn. Beware of the sharp thorns when harvesting hawthorn, eye scratches from thorns can cause blindness.

Legends, Myths and Stories

In ancient Greece and Rome, the hawthorn had happy associations, being linked with sweet hope, marriage, and babies. Dedicated to Hymen, the god of marriage, the hawthorn was used as a symbol of hope at weddings in Greece; bridal attendants wore its blossoms while the bride carried an entire bough. Also, in both Greece and Rome, torches carried in wedding processions were made of hawthorn. The Romans put hawthorn leaves in the cradles of newborn babies to ward off evil spirits.

In medieval Europe, hawthorn had an entirely different image. Generally regarded as an unlucky plant, it was thought that bringing its branches inside would portend the death of one of the household's members. Hawthorn was also one of the witch's favorite plants and was especially to be avoided on Walpugis Night, when witches turned themselves into hawthorns. With a little superstitious imagination, the hawthorn's writhing, thorny branches at night probably do look enough like a witch to have instilled fear in medieval folk.

The Chinese sell a jam of hawthorn in shops under the name Shan-cha-kao or Shan-cha-ping.

Hawthorn is the plant for which the ship Mayflower was named.
