Many of us think of mistletoe as a little twig with green leaves and white berries, tied with a red ribbon and hung in doorways during the holidays, where it is a popular tradition to stand under and receive a kiss. However, mistletoe has a long and much more interesting history.

Mistletoe, Phoradendron flavescens, is common in North America, but there are hundreds of species around the world. Mistletoe is also known as birdlime mistletoe, Herbe de la Croix, Mystyldene and Lignum Crucis. Mistletoe is a parasitic plant propagated by birds. Birds eat berries and then defecate on tree branches, and with some luck, the seeds germinate.

Mistletoe does not grow in the ground like most other plants; it derives all of its nutrients from its host tree. In early history, mistletoe was considered to be an outgrowth of the tree. It will grow on almost any deciduous tree, but really likes the soft bark of old apple trees. Mistletoe is an evergreen plant that grows 2-5 feet in diameter.

The following are interesting facts and folklore about mistletoe:

  • Norsemen were allowed to steal a kiss from any woman caught standing under the mistletoe; refusing the kiss was considered bad luck.
