Against the frost risk in Goyang-si
Why these dates
Sow direct three weeks before the last frost and thin to 20cm. It flowers for about six weeks and then goes to seed, so sow a second batch three weeks later if you want it into late summer. Leave the last flowers to pod and it will sow itself for next year.
Hardy to about -10C, so an autumn sowing overwinters easily in zone 7 and warmer and flowers in late spring. Short-lived in heat and finished by midsummer in a hot climate.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Love-in-a-mist are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Goyang-si.
Hardiness is not the obstacle here. Goyang-si is zone 7a, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
The median frost-free season here is 223 days, against 70 to 90 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
