CharacteristicsEdit

The English name "hackberry"[4] refers to the fruit, which is astringent due to their tannin content.[5]

There are two varieties:

  • European bird cherry Prunus padus var. padus, Europe and western Asia.
  • Asian bird cherry Prunus padus var. commutata, eastern Asia.

The flowers are hermaphroditic and pollinated by bees and flies. The fruit is readily eaten by birds, which do not taste astringency as unpleasant.

Bird-cherry ermine moth (Yponomeuta evonymella) uses bird-cherry as its host plant, and the larvae can eat single trees leafless.

PoisonEdit

The glycosides prulaurasin and amygdalin, which can be poisonous to some mammals, are present in some parts of P. padus, including the leaves, stems and fruits.[6]

UsesEdit

The fruit of this tree is seldom used in western Europe, but, once upon a time, it may possibly have been commonly eaten farther east. According to Herodotus writing some 2,500 years ago, a strange race of men and women, all bald from birth, whom live in what may possibly be the foothills of the Urals, pick the bean-sized fruits of a tree called 'pontic' to make a black juice from, and from the leftover lees of the fruit make a cake-like dish, this juice and cakes being the main sustenance of the bald peoples. According to A.D. Godley, a translator of the works of Herodotus published in the early 1920s, it is said that the Cossacks make a similar juice from Prunus padus, and call this juice a similar name as the bald men called their juice according to Scythian traders according to Herodotus.[7]

It was used medicinally during the Middle Ages.[clarification needed]

The bark of the tree, placed at the door, was supposed to ward off plague.[clarification needed]

The variety commutata is sold as an ornamental tree in North America under the common name Mayday. It is valued for its hardiness and spring display of fragrant, white flowers.[8] The common name Mayday tree is not related to the distress signal mayday as the name for the tree was in use prior to the adoption of mayday as an international distress signal.[9]

A taboo on the use of the wood was reported by natives of Advie, in northeast Scotland, being regarded as a "witches tree".[4]
