Why these dates
Sow in late summer, roughly ten weeks after midsummer, for picking from late autumn onwards. It self-seeds freely, so one deliberate sowing often becomes a permanent patch.
Hardy to about -12C and unbothered by repeated freezing, which is why it was a winter green long before it was a salad leaf.
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. Claytonia are timed for direct sowing 10 weeks after it, and this page simply resolves those offsets against the frost date computed for Al Fayyum.
