Chinese artichokes through the year
Against the frost risk in Kansas City
Why these dates
Plant tubers around the last frost date and leave undisturbed all season. Lift after the top growth has died back in late autumn, and expect to miss a few.
Tubers are hardy to about -8C in the ground and are best left there and dug as needed, since they shrivel quickly once lifted.
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. Chinese artichokes are timed with planting out 0 weeks after it, and this page simply resolves those offsets against the frost date computed for Kansas City.
The median frost-free season here is 195 days, against 180 to 210 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
