Globe artichokes through the year
Against the frost risk in Shijiazhuang
Why these dates
Start indoors 8 weeks before the last frost and plant out after it, or buy offsets. First-year plants give a token crop; the second and third years are the productive ones. Replace with offsets in the fourth.
The crown survives to about -10C with a dry mulch over it, considerably less in wet ground. In cold regions it is often lifted or heavily covered.
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. Globe artichokes are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Shijiazhuang.
Hardiness is not the obstacle here. Shijiazhuang is zone 7b, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 2, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
