Romantic for some, but not for the trees it grows on.

The other day, I saw a show of parasitic mistletoe.
It sucks the juices from the wood, which does not do it any good.
Birds eat its seeds1, which go right through and stick on to a branch in poo,
Or get spat out (just for the thrill), or maybe wiped off from their bill.

Christmas picking does no good: once mistletoe’s invaded wood,
Its hypocotyls2 get a grip and add haustoria3 at their tip.
The poor host plant is out of luck: those darned haustoria can suck
Its nutrients; and, as you know, they’ll help the mistletoe to grow.

To rid a plant of mistletoe, all affected wood must go.
Or, if you like, it would be fine to harvest it at Christmas-time
And sell it – you can charge a lot. Say, “This is good for you-know-what:
Just hold it up above her head and soon the pair of you’ll be wed!

1. Actually, drupes, because each has a ‘stone’ inside; the actual seed is inside the ‘stone’. But no-one uses ‘drupes’ in ordinary conversation.
2. The part of the stem of an embryo plant beneath the stalks of the seed leaves (cotyledons) and directly above the root.
3. A haustorium is a special organ of parasitic plants, which invades host tissues and serves as the structural and physiological bridge that allows the parasites to withdraw water and nutrients from the conductive systems of living host plants.
