Agreed. I was wondering how Rusty could be so sure by the words only.
I thought the OP was talking about a regular globe artichoke, Rusty
didn't. shrug That's why I supplied pictures. If there was
anything in there as a visual reference, it didn't make the xpost to
rfc.

It's not really the season for globe artichokes, but it is for the manky
artichoke weeds. Well, in the UK, anyhow. Not sure where the original
poster was now.
