Celery, Par-cel, Celery leaf and Celeriac

Have you tried Lovage, Vinny? Its part of the same family as Celery and is very definitely perennial. Its pickable throughout the year - I could cut a bunch of it now. Celery-ish taste.

I've tried it ,it's the 'ish' bit I am not keen on. Has too strong a taste for my liking! Each to there own though!
It's really surprising how few leaves of kin-sai you need to flavour soup. I once made Jamie Olivers 'Zombie brain' out of a large celariac head. It was totally disgusting. (As a zombie brain probably would be?) I love cream of celery soup though.
