Another coriander fan here - love the stuff! (especially in butternut squash soup)
The title of the thread reminded me of the flat-leaved parsley in my salad bed, currently known as The Parsley That Would Not Die

Each time we've had a hard frost it has wilted, only to spring back up bigger and greener than before! Maybe it's the chicken manure I spread on the bed after I cleared up all the tatty remains of the old salad leaves...
