Against the frost risk in Queens
Why these dates
Sow onto warm soil two weeks after the last frost, barely covered. It germinates badly in cool ground and then grows very fast once summer arrives.
Killed outright at 0C. This is a high-summer crop with no cold tolerance at all.
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. Purslane are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Queens.
The median frost-free season here is 249 days, against 40 to 55 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
