Cardoon in Zone 7a & 7b
Cynara cardunculus
When to plant cardoon in zone 7b
Zones 7a and 7b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Cardoon needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Feb 20–Feb 27 |
|---|---|
| Direct sow / transplant outside | Apr 24–May 1 |
| Estimated harvest | Aug 22–Aug 29 (~120 days after transplanting) |
Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 3-4 ft.
Cardoon is a close relative of the globe artichoke already covered on this site, but instead of harvesting a flower bud, it's grown for its thick, blanched leaf stalks, a classic Mediterranean vegetable most American gardeners have never grown.
How cardoon fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Cardoon needs about 120 days from transplant to first harvest.
