Thank you to everyone who helped me identify that the weed that seems to be rampantly growing in a lot of the plants I ordered is in fact LIVERWORT. Having never come across it before, I am gob-smacked at how prolific it is and how it appears to have got into every variety of plants I ordered.
From 10 x 9 cm pots of DIANTHUS ‘Deltoides’ resulted in this impressive pile and even what looks like a stray POPPY.
The examples I found within the PULSATILLA ‘Mixed’ were particularly impressive. There was also, again another variety of plant that didn’t belong in the pot. Again, the pile below is from just 10 x 9 cm pots!
Thankfully, only one of the AQUILEGIA ‘Black Barlow’ had any sign of the unwelcome imposter and that was quickly removed.
There were a couple of pots of AUBRIETA ‘Red Cascade’ which I found some in too.
So all in all, I feel as though I now have a new nemesis!!!!
