8-12 weeksPlant develops deeply lobed, silvery-green leaves on tall thick stems; reaches 3-4 feet tall and wide
Water regularly, stake or support plants if needed in windy areas. Apply 2-3 inches of mulch. Fertilize every 4 weeks with balanced fertilizer.
Bud Formation
3-4 weeksTight, compact green buds appear at stem terminals and leaf axils; buds are oval-shaped and 3-5 inches long

Bud Maturation
2-3 weeksBuds enlarge, scales tighten, color deepens to vibrant green; buds feel firm and compact
Monitor daily for harvest readiness. Maintain soil moisture. Stop fertilizing to concentrate flavor.
Harvest

Harvest Tips
Harvest buds when they are firm, 3-5 inches long, and scales are tightly closed—before any purple coloration appears or scales begin to spread. Cut with a sharp knife, leaving 1-2 inches of stem. Cut from the top main bud first; this stimulates production of smaller secondary buds along the stem. Continue harvesting secondary buds for 6-8 weeks. Peak harvest occurs in spring and fall.
Fun Facts

- 🌱 Artichokes are one of the oldest cultivated crops, with evidence of use dating back to ancient Greece and Rome, and are native to the Mediterranean region.
- 🌱 A single mature artichoke plant can produce 15-20 buds per season if properly managed and secondary buds are harvested, making it very prolific for home gardeners.
