I don't think that's white bryony. Never heard it called English Mandrake
I have white and black bryony, 2 species of bindweed and a proper mandrake. still not sure of this one.
The way the stem comes off the root in the first pic of the second batch looks wrong for bindweed.
The leaves are the wrong shape for White Bryony
I've had one plant of black bryony for years and it's never spread.
is there something we haven't thought of?
