In warm climates, USDA zone 8 and above, artichokes are grown as perennials. In zones 5-7, artichokes are annuals.

Perennials: Most artichoke varieties are hardy to around 20F. If your area gets colder during winter months, the artichoke plants will need protection. Start seeds outdoors or indoors in spring or fall. Transplant outdoors when they are a few inches tall. It takes two years for plants to flower.

After the first frost, cut the plants down to 12” and place a wire cage around each one for support. Full the cage with layers of compost, straw, and leaves, and cover with tarp.

Annuals: Start seeds indoors 8-10 weeks before the last frost. Put the plants out in mid-spring to prompt bud setting – this process tricks them into thinking they've been through a winter. Artichokes need a chilling (not freezing) time to produce buds the first year and operate as an annual. Keep them outside for 10 days when the temperature is around 50F. Bring them inside again if there is threat of freezing temperatures.

Plant artichokes in full sun in sandy, well-draining, rich soil. Arrange plants 4-6 feet apart in rows 7' apart. Water consistently and deeply. Artichokes require frequent watering to produce plump flower buds (the part you want to eat!). If not watered enough, the buds won't be as well-developed or tender. Mulching around the plants to keep the soil cool and retain water is highly recommended.

Harvest the buds before they produce flowers. Each plant should produce between 6-10 artichoke buds
