Ah you beat me to the punch with the bean reference in The Unicorn Spell. It smells more like a lima bean to me, but that's just splitting hairs. I really like the frag, although it ends up a bit too feminine on my skin.
I also got a bit of carrot in Dior Homme. It's been so long I can't offer a good perception of the scent in general - I just know that I liked it on my skin, but didn't think I'd feel comfortable actually wearing it regularly and so passed on this one.
Celery (faint) in Grain de Plaisir - but honestly I get a stronger nutty/doughy accord there. The nutty/doughy accord is excellent. The celery is faint and fresh and quite enjoyable, too.
