Globe artichokes (Cynara scolymus) — perennial.

Unlike an annual crop, the work here is front-loaded into establishment: get the planting and the site right and the same plants crop for several seasons.

Core growing advice on this page is checked against named horticultural and university-extension sources — see References.

Stage BBCH Notes
Sowing and raising young plants 0 Sow indoors late winter to mid-spring, about 2cm deep in modular trays or small pots, or direct outdoors in spring once soil has warmed; transplant when plants have at least five large leaves and are about 30cm tall (RHS).
Planting out and first-year establishment 1 Plant out at 75-90cm spacing after the last frost, hardened off first; remove any developing flower stalks in the first year so the plant puts energy into establishing strong roots (RHS).
Overwintering and spring regrowth 3 Top growth dies back in autumn; young plants need thick mulch plus cloches or fleece in hard frosts, established plants benefit from covering the crown with spent foliage and straw/bracken/compost mulch, then re-sprout in spring (RHS).
Budding and harvest 8 From the second summer, harvest flower buds from June onwards at full size but still tightly closed, cutting with secateurs above a leaf joint; a mature plant can produce up to 12 buds a year (RHS).

When to pick: RHS: young flower stalks removed in the first summer; a full crop of buds is produced in the second summer, harvested June to September. Harvest "when the flower buds are still tightly closed", using secateurs, "before the bracts start to open" — check regularly as buds open quickly in warm weather. Cornell: most gardeners remove and eat the flower head and bracts before they open, harvesting the hearts before flowering.

Storage

Best used fresh soon after cutting
