Sow indoors from February on in individual pots 2 seeds per pot about 2-3 cm deep. Cover the seeds with sowing soil because artichokes don't need light to germinate. Put the pots in a warm room or in a propagator. Thin to 1 strong seedling when the seedlings are large enough to handle.
Transplant the seedlings in may (avoid frosts) outdoors to 1 meter apart. Artichokes need a warm sunny spot with free draining soil. Keep weed free and moist.
Sow outdoors from April on, when the day temperature is about 15 °C. Sow 3-5 cm deep and cover the seeds with sowing soil. Thin when the seedlings are about 15 cm tall to 1 meter apart.
Harvest your artichokes when the buds are large but closed. Cut of the bud with a piece of stem attached to it. Use the artichokes the same day. Wilted buds can be refreshed with cold water.
