Vietnamese coriander through the year
Against the frost risk in Sétif
Why these dates
Plant out after the last frost. Grows from cuttings in water within days; seed is rarely available and rarely needed.
No frost tolerance at all. Overwinter a cutting indoors rather than trying to protect the plant.
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. Vietnamese coriander are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Sétif.
Sétif sits in zone 9a, which is colder than this crop is rated for, so it will need winter protection or a container that can be moved under cover. The dates below still describe the right time of year; the open question is survival rather than timing.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 1, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
