Virgo ends summer. Mutable and earth: the harvest sign, where what grew is sorted, kept or discarded.
Mercury rules it, in its analytic register rather than its communicative one. The traditional attention to flaw and detail is the work of a harvest — most of the labour is rejection.
The Sun leaves Virgo at the September equinox, so the sign spans the last stretch of longer-than-night days.
