But I've already missed Christmas, you say. No, I'm not collecting mistletoe in order to get extra kisses, although it might be a tradition worth encouraging in Australia. From what I can tell, the Europeans are winning in the mistletoe respect stakes, but I've become quite intrigued by it in the last few years. My inner ecologist is delighted, my inner horticulturist is horrified. Horticulture training recommends the removal of mistletoe from trees and shrubs as quickly as possible, as they can cause water loss and death in some cases. These clever plants are considered parasites, but I prefer to think of them as piggy-backers. When a seed germinates on a branch, the root grows into the host plant and proceeds to live off its water and nutrient supplies instead of growing its own root system and getting these from the ground the old fashioned way. The downside for the generous host is that in general, mistletoe is greedy and wasteful, allowing water to escape from the leaves that is normally trapped carefully by waxy cuticles and closed pores.
But it's not all bad news... mistletoe berries are an important food source for Mistletoe Birds and the nectar is a nutritious food for Painted Honeyeaters, among others. I wouldn't mind having some of these sweet birds visit my backyard, and so I decided to try and infect (or introduce) some mistletoe into my plants. Until today, that wasn't as easy as it seemed. You can't simply transplant it, as it's anchored into another plant... so the only option is to plant a seed. Again, not so easy, as the berries are eaten by well-meaning birds and spread all over the place. I've been watching the whole process, as the flowers opened a few weeks ago, and the berries have now followed. Imagine my excitement in finding some berries on the ground under a bottlebrush tree in my street! But if I'm realistic, I know the seeds will germinate much better if they have been pre-digested by a helpful feathered friend.
Hence the visit to the large Silky Oak tree. There are so many mistletoes here that the birds hang around for ages, depositing their packages of seedy goodness as they feed and play.
I graduated from my horticulture degree this month, and 6 years ago I'm sure I wasn't imagining collecting bird poo from the ground when I enrolled. But what I also didn't anticipate was how exciting I would find it. I've waited patiently for months for these sticky little deposits, and I'm rapt to be attaching them to my own bottlebrush tree so that I can have the wonderful mistletoe birds to watch on a regular basis. I can't wait to see if they grow!
I'm even planning to try some seeds on my lovely big gardenia, as it's right next to our birdbath and might be extra encouragement for shy birds. Some mistletoe were growing on the Crepe Myrtles in the street, so I know they're not too strict about who they piggyback onto.
If anyone is interested in Australian mistletoe and its importance to the environment, this short radio interview is worth listening to. It was extra inspiration for me to get out there and find some seeds!
