Mistletoe: Not Just for Kissing
by Alan Pulley - posted 12/21/11

 

Tis the season for mistletoe! Most would agree that the Christmas season and mistletoe go hand in hand. I remember my dad shooting it out of the trees when I was a youngster.  According to folklore, after every kiss under the mistletoe one of the berries was plucked, and once all the berries where gone, there was no more kissing.

American mistletoe can be found all throughout eastern and southern forest of the US, and is especially fond of maple trees. It’s unveiled each year when the last of the leaves fall from the trees and reveal their clumps of green, ball-shaped foliage growing among the tree branches.

There’s more to mistletoe than just holiday tradition. Believe it or not, it plays an important part in our ecosystem. Mistletoe is a host plant for the great purple hairstreak butterfly, and is the only plant that its larva will eat.

Mistletoe is also a good winter food source for birds. Birds feast on the female mistletoe’s white berries, which are toxic to humans, and then spread the sticky seeds to other trees through their droppings. From there it takes root into the tree. It’s considered a hemiparasite because it doesn’t live entirely off the tree. Mistletoe generates its own photosynthesis; however, it does depend on the tree for its food and water, enough so that the tree could die from a heavy infestation – but in most cases, that’s not the case.

For the most part, this unique native is harmless and its benefits to wildlife and our holiday enjoyment outweigh its potential invasiveness.

I want to personally wish everyone a happy and safe holiday!!

enjoyed the info on the mistletoe, especially the part about the hairstreaks. We have a lot of it, especially in the oak trees.

Thank you Lynn. I didn't mention it but it does like to grow in oaks. Have a Merry Christmas!

Hi, I was looking up mistletoe recently ('tis the season to be curious about it) - is it Phoradendron leucarpum that you are describing? Or has the European mistletoe(Viscum album) infested our trees?

Hi Ellen,

Great question, sorry for not being clear. I was referring to the common eastern American mistletoe (Phoradendron leucarpum). European mistletoe (Viscum album) resembles the American mistletoe and host damage is typically similar to that caused by American mistletoes, but its range is limited to the west coast (California), based on my research.
Healthy trees are able to tolerate a few mistletoe plants with little to no harmful effect; however trees that are heavily infested with mistletoe over a period of several years may become less vigorous, stunted, and can possibly be killed if subjected to stress from drought, extreme temperatures, root damage, insect infestation, or disease.

Wow, I had no idea that it was the host and only plant the Purple Hairstreak will eat...that's interesting!

Thanks Jan, who would have thought, right? Everything in nature has its purpose - even mistletoe.
