Osculate Me Under the Obligate Hemiparasite

Welcome to December and all the seasonal festivities and frivolities married to it! Few holidays have such a diverse number of traditions and customs. I mean, who came up these and why are they related to Christmas: eggnog, fruitcake, decorated conifers, socks on mantles, and swapping spit under mistletoe, just to name a few (and those are only the decidedly American holiday traditions. You should hear what they do in other countries!).

Actually, we did borrow the mistletoe thing from Britain, like most things which are so awesome and British. And the British being born gardeners, well, they know a thing or two about plants. What other culture would write a Christmas carol about holly and ivy? As the great global melting pot, not only do we often borrow foreign customs, we frequently take their plants, too. Viscum album, the native species found in Great Britain and much of Europe, having now been introduced to North America, is an evergreen plant with a woody stem which grows on and gets most of its nutrients from a host. It does photosynthesize a bit, but not much, which is what makes it a hemiparasite, and that's a compliment, really. The Latin name is likely derived from the sticky seed coating (viscum) and the color of the berries (from 'albus', meaning white).

The species native to Spain, Portugal, North Africa, Australia, and Asia is Viscum cruciatum (sounds like a Harry Potter spell, doesn't it?).

All in all, there are over 80 genera with more than 900 species of Mistletoe. And the family name that these plants belong to? Wait for it....Santalaceae.

I kid you not, but it has nothing to do with Santa Claus. (Or does it? Nah.) Mistletoe is related to Sandalwood. It also happens to bloom and set fruit right around Christmas time when most other plants in the Northern Hemisphere are settling in for a long winter's nap. Once dissected, the common name is anything but complimentary. The name mistletoe comes from the Anglo Saxon word 'mistel' (which means dung, probably a reference to how the plant is propagated) and the Old English word 'tan' (which means twig). Roughly translated, mistletoe means 'poo on a stick'. Isn't that...special!

Mistletoe has been known and used in Herbalism for centuries and parts of the plant were prized by many ancient cultures for their healing properties. The Greeks used it to cure everything from menstrual cramps to spleen disorders, while over in Rome, the naturalist Pliny the Elder noted its use as a balm against epilepsy, ulcers and poisons (ironic, since the berries are poisonous to humans).

The plant’s romantic associations most likely began with the Celtic Druids of the 1st century A.D. Since mistletoe can blossom even during the frozen months of winter, the Druids came to view it as a sacred symbol of vim and vigor, and it was administered to humans and animals alike in the hope of restoring fertility (again, poison! Raising eyebrows, here). The association with fertility and vitality persisted throughout the Middle Ages. Some considered it an aphrodisiac (Poison! Does no one listen!?) owing to the allegedly sexual nature of the plant: the Y-shaped branches, white sticky juice from pearl hued ball-shaped berries hinted of...let's not venture further...ok, lets. Ironically, it's the female plant that bears the poisonous fruit while the male plant is conspicuously berry-less. Let your Freudian brain puzzle that one out over a mug of 'nog for a while.

By the 18th century mistletoe had become incorporated into Christmas celebrations around the world. The 'downstairs' class of Victorian England is credited with first recording the tradition of kissing underneath the mistletoe. Taking their cue from the Druids' and their fertility rituals, the tradition of kissing beneath the mistletoe dictated that a man was allowed to kiss any woman standing underneath the boughs, and should any woman refuse the overture, ill luck would befall her. Another variation on the tradition stated that with each kiss a berry was to be plucked from the mistletoe, and when all the berries were gone, the smooching must cease. Many a serving maid scurried into hiding when the mistletoe was hung, as described by nineteenth century writer Washington Irving: "the mistletoe, with its white berries, hung up, to the imminent peril of all the pretty housemaids."

"Ah, what an excellent specimen of Viscum album! Did you know this lovely plant is actually a parasite!? Why, it's extraordinary, really! You see, it actually grows in the branches of trees, not in the ground! Yes, isn't it remarkable? The seeds are eaten by birds, whereupon they pass through the digestive tract, or gut, and are shat out onto a tree branch where the seed sprouts by sending out rooting tendrils called haustorium..."

"Will he ever shut up and just kiss me?"
Kissing under the mistletoe caught on, surprisingly, and continues as a holiday sport to this day. I suppose of all the wacky Christmas customs, smooching under a parasitic plant is more pleasant, and infinitely more preferable, to a regifted 10-year old fruit cake.

So while you're enjoying the eggnog and petrified fruitcake at your next holiday gathering, keep an eye out for halls decked out with that most romantic of evergreens, pucker up, and whisper seductively to your sweetheart, "Osculate me under the obligate hemiparasite". That'll get hearts racing, I guarantee it!

Double Trouble

"So we grew together, like to a double cherry, seeming parted, but yet an Union in partition. Two lovely berries moulded on one stem; So, with two seeming bodies, but one heart"

~ William Shakespeare, A Midsummer Night's Dream

Spring Is Come

Behold, my friends, the spring is come; the earth has gladly received the embraces of the sun, and we shall soon see the results of their love.

October

"Very much a favorite month, this. Even writing a capital O at the start of its name is a pleasure. Of course, the weather can be foul; when can't it? But October does give us spells of the most delectable weather, too, and the golden warmth of its light invests everything with its glow. Nights have a nip in them but by day the air is soft again and we just need to relax in appreciation."

Are You My Mum?

Autumn is coming, whether (or should that be 'weather'?) we're ready or not! A heat wave last week sent fall annuals into overdrive so mums are fully blown, but the mild summer also means summer annuals and perennials are still growing strong. Ack!

Still, one must prepare for the inevitable so I did what any sensible gardener would do: I paid a visit to Longwood Gardens PG Class of 2015's greenhouse.

Second year students in the PG program enjoy an educational trip abroad focused on horticulture and public gardens, and are responsible for raising half the funds for the trip. Part of their fund raising effort includes growing and selling plants at three major sales during the year. 

This week is their Fall plant sale but I was allowed to pre-shop (one of the perks of being an alumna!). Guess what I'll be doing at work this week?


Thanks to Nick and Lincoln, PG Class of '15, for helping me load the truck!
