Arum maculatum, which has poisonous berries…. Hmm.
This stuff is spreading! It’s a trio now!
I guess I should have expected that, since somehow it appeared in my garden.
Note that this plant was at the same stage on 7 May last year. For whatever it’s worth….
The meaning of “weed” in the title is from The Botanist: “any plant that’s growing where you don’t want it.”
