Growing Artichoke in Zone 10A

Artichokes are dramatic, architectural plants that produce edible flower buds. In cool, mild climates they’re perennial; elsewhere grow as annuals.

Zone 10A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

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
