Artichokes can be produced from seeds. Commercial culture is limited to warm areas hardiness zone 7 and above. Artichokes require good soil, regular watering and feeding, plus frost protection in winter. Before frost, cut back to 15cm (6") and mulch with soil, straw or leaves to keep the root from freezing. Uncover in April. Offshoots of these plants should be set out in the spring, so that the older plants can be replaced after a few years.
