Chervil is one of the classic French fines herbes, a delicate, anise-and-parsley-flavored annual that fades fast once cut or cooked, which is why it's almost always added at the very end of a dish rather than during cooking.
How chervil fits zone 9's season
Zone 9b's frost-free window runs about 293 days, from February 15 to December 5. Chervil needs about 60 days from sowing to first harvest.

Zone 2 sows before zone 3 here, which looks wrong and is not. USDA zones rank winter cold, not season length, and zone 2 is mostly interior Alaska, where hard winters come with warm summers. More on what a zone measures.
