Cilantro is a short-lived crop in most climates: it wants cool weather, grows fast, and bolts to flower the moment heat sets in, converting its leaves' flavor from bright and citrusy to soapy and thin almost overnight.
How cilantro fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Cilantro needs about 50 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.
