Purple sprouting broccoli through the year
Against the frost risk in Nizhniy Novgorod
Why these dates
Sow around ten weeks after the last spring frost, plant out into firm ground, and leave it standing all winter. Spears come in late winter and early spring, months after sowing.
Hardy to roughly -12C and needs a cold period to initiate spears at all, so a mild winter can leave the plant leafy and unproductive.
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. Purple sprouting broccoli are timed for direct sowing 10 weeks after it, and this page simply resolves those offsets against the frost date computed for Nizhniy Novgorod.
The median frost-free season here is 155 days, against 220 to 300 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
