Artichokes are dramatic, architectural plants that produce edible flower buds. In cool, mild climates they’re perennial; elsewhere grow as annuals.
Top Growing Tips
- Needs vernalization (cold exposure) to trigger budding — start indoors early
- In zones 7+, plants return every year from the roots
- Harvest buds before they begin to open for best eating quality
- Each plant can produce 6-12 buds per season
- Cut stalks to ground after frost for spring regrowth
Companion Planting
Good companions: tarragon, sunflowers, tomatoes
Avoid planting near: brassicas, fennel
Harvest Timeline
85-100 days from transplant; harvest when bud is still tightly closed
