Mistletoe - Not Just For Christmas

Mistletoe seems to be everywhere this year. At the Rococo Garden and all through the Painswick Beacon up to Minchinhampton, the trees seem laden.

Mistletoe belongs to a rather large and complicated family. In the plant world parasitism had only evolved nine times and of these the plants which make up mistletoe have evolved independently 5 times creating families Misodenraceae, Loranthaceae, Santalaceae, and to complicate things here, the modern family Santalacea contains the old Viscaceae & Ermolepidaceae.

Our Mistletoe, common European Mitstletoe, Viscum album (Pictured Left) belongs to the family Santalacea, and is the only species native to the United Kingdom.  There are a number of sub. species belonging to the species Viscum, including Viscum album subsp. austriacum, with yellow fruits preferring larix and pines as its host.  It is uncertain where the name Mistletoe came from but many think it comes from the German Mist, for dung & Tang for branch.  This could be due to it being spread in bird dropping as they move from tree to tree.  If you have ever read old english herbal’s which I have written about before or really old cook books, you will have heard of mistel. This is the old English for Basil and not Mistletoe, which is not edible and will give you a rather unpleasant bout of diarrhea and a low pulse if digested.

Our mistletoe is unmistakable with long broadly ovate green leaves always occurring opposite each other, fairly brittle woody stems and clusters of up to 6 waxy white berries.

European mistletoe grows on a fairly broad range of host trees but it is particularly fond of old orchards in the English Countryside.  Lost to parts of the South Coast it is particularly prevelant in the rolling subtle Herefordshire landscape.  Mistletoe has developed a form of hemi-parasites, which means, that in most species it develops evergreen leaves which are able to photosynthesis and therefore using the host predominantly from water and mineral nutrients only.  In most cases it will only reduce the vigour of its host shrub or tree, but with heavy infestation this removal of resources  from the host can kill it.  In such a large family there are some odd exceptions such as the Cactus Mistletoe, Tristerix aphyllus, native to the Andes, Chile and Columbia which lives deep inside the vascular tissues of its hosts appearing only to flower with rich red flowers once a year. Before rushing out to the Garden Centre with a renewed interest in Rhipsalis baccifera, it is not this plant, although this was brought from the New World as a Mistletoe substitute.

In Europe Mitsletoe is generally spread by the Mistle Trush and is a source of food to many grazing animals which help transfer pollen between species.

The smallest known mitsletoe species. A minutissimum lives only  on Pinus wallichiana,a stunning, afghan hound,like pine, both native to the Himalaya’s.

The Mistletone most Americans will be familiar with and grown as a harvestable crop for Christmas decorations is Phoradendron flavescens.  Known as the Eastern Mistletoe this has shorter broader leaves and longer clusters of up to 10 berries.  Phoradenderon is in the family Santalaceae, like our own, but has over 35 species.

One I particularly like and it’s not for purists, is Phoradendron californicum, the mesquite mistletoe.  Native as the name suggests to Southern California it grows in the Mojave and Sonoran Deserts under 4000 feet.  Its a leafless species which sends out tiny, heavenly fragranced flowers in winter which are followed on the female plant by beautiful berries in shades of copper, garnet and dusky pink.

Oddly the numbers of mistletoe species are much large in the Subtropical and Tropical climates with 85 species in Australia and 900 genera in the family Loranthaceae.

Now not much more need be said of mistletoe and Christmas, our traditions of keeping some in the house from December through the year for good luck is largely unheard of in Europe, we are all agreed however that it is the last of the Christmas Greens to be removed from the house after Candlemas, so it remains for 40 days as stated in the Torah.

The other tradition we all take up, some not knowing its full history is the kissing.  This comes from Scandinavian Mythology. Baldr was a god who was associated with light, beauty, love and happiness. His mother Frigg prompted by a prophetic dream, made every plant, animal and inanimate object promise not to harm him.

But Frigga overlooked the mistletoe plant — and the mischievous god Loki took advantage of this oversight, tricking the blind god Hoor into killing Baldr with a spear fashioned from mistletoe. Baldr's death brought winter into the world, until the gods restored him to life. Frigga declared the mistletoe sacred, ordering that from now on it should bring love rather than death into the world. Happily complying with Frigga's wishes, any two people passing under the plant from now on would celebrate Baldr's resurrection by kissing under the mistletoe.

Frigg herself has some lovely associations, such as Galium verum, known as Friggs Grass.  Frigg was associated with married woman and Scandinavians used this grass due to its sedative qualities during child birth.

I know this has been a rather long post, but I will not be posting again until the New Year when, and not to keep you on tender hooks, I will have some exciting news.

This is possibly one of the most interesting articles I have read about mistletoe. You have written about types I did not know even existed. Absolutely fascinating!

Scott said...

Lovely photo's, I never knew so many different types existed!!

Thank you both, I think mistletoe is one of the interesting groups of plants which encompass much more than one first thinks of. I actually really enjoyed refreshing my memory on them and finding out new information on particular species such as Phoradendron canzacotoi which is a tropical species and very distinct to our own mistletoe.

Paul, Wow!
Yet another well thought through, intelligent and eye opening post!
I never knew mistletoe was so diverse, how do you amass all your knowledge?

A very interesting post about mistletoe! It's good to know the full story about the kissing tradition. We have mistletoe growing in the tops of our oak trees. I found your blog by way of Blotanical. Welcome! It's a great community, and I know you have lots to contribute. Merry Christmas!

You seems to be an ardent lover of Gardening. Like your blog with wonderful picture of plants. Keep it up the good work. Happy Gardening.

I have to admit that I think the English Mistletoe is prettier than the Mistletoe that we have on the west coast in the US. I like the longer stems.

Paul Hervey-Brookes said...

Allison, Debs, Flowers & Cindee thank you for your comments. On the traditional American mistletoe its got the edge on berries so I think its an equal split, however you have something like 50 species across the country where we have just the one so I guess it has to work extra hard!
