Can anyone tell me what this plant is, stalk is approx 20mm thick.
one or the Arums. Arum italicum or A. maculatum most likely
One to be wary of!
It's an arum.I had one in the garden many, many years ago and I let the seed fall.Every year since, I've been hoeing up seedlings from all around the garden. They're almost impossible to remove once they start seeding.A lovely plant, but incredibly invasive and a tiny bulblet will sprout from well over 1ft below ground
