Against the frost risk in Shuangcheng
Why these dates
Sow direct two weeks before the last frost. Do not transplant - the taproot forks if disturbed and becomes unusable.
Very hardy, to -15C, and left in the ground over winter to be lifted as required.
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. Salsify are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Shuangcheng.
The median frost-free season here is 162 days, against 120 to 150 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
