You might not recognise the name, but you will certainly know what Marchantia (common name Liverwort) are - they form flat plates of shiny green growth on the surface of pots, with strange round suckers or sockets, looking like some sort of organic Lego.
Then, without warning, they will suddenly send up a miniature forest of tiny palm trees, less than an inch high (oh, all right, less than 2.5cm grumble grumble) but perfect in shape and form. I suppose that someone, somewhere, must like them, but this year they are driving me mad.
Presumably in response to the pathetic summer that we have had, my front garden has been infiltrated by these slimy little bryphoytes (ok, they are not actually slimy, but they look as though they ought to be) and I have spent all summer going round all the pots in the garden on a Forth Bridge basis, scraping them off, and topping up the soil.
And then I found the poor little fellow in the photo, above. Earlier in the year I'd pruned one of my Thujopsis dolobrata, and had pushed one of the offcuts into a small pot of soil: they are incredibly easy to propagate, as that is, quite literally, all you have to do. Somehow, he'd avoided scrutiny for the best part of the year, and look at him now! You can barely see the plant for the weeds! hangs head in shame
So I guiltily scraped off the liverworts, checked his roots (coming along nicely), topped up the soil and put him back out, having made a mental note to be a bit more concientious in future.
I have never been troubled with liverworts until the last year or two: is this a sign of climate change? Or is my front garden getting damper? Am I watering too much? Certainly I have at least two frogs living in it, which explains why I have no slugs... I still have snails though, so if anyone knows a thrush who is looking for a nice place to live, please send them along. Anvil stone provided.
