Growing ArtichokesCultural requirements Artichokes are native to the Mediterranean. In warm areas, (zones 8 & 9) such as California, artichokes can be treated as perennials and left in the ground for 6-7 years until they need to be divided. In colder regions, artichokes should be treated as annuals as the roots will die with prolonged freezing. Plants grow 4 feet high and 6 to 8 feet wide with silvery-green leaves. Artichokes form from big flower buds and if left to grow, will blossom into beautiful, purple ornamental flowers. Planting & growing instructions Plant roots in Winter or in Spring in cold areas. Plant crowns 6 to 8 inches deep and 6 ft apart in well-drained soil, rich in organic matter. If treating as annuals, use closer spacing between plants. Protect with shade in hot areas (soil temperatures above 85ºF will prevent bud-setting). After growth starts, water thoroughly once a week, wetting entire root system. Susceptible to aphids, snails, slugs and gophers. Use Peaceful Valley's gopher baskets or wire in areas where gophers are a problem. Harvest buds while they are tight and plump. When leaves start to yellow, cut off old stalks near the ground. In cold-Winter areas, cut tops to 1 ft in Fall. Roots do not tolerate prolonged freezes; mulch heavily to protect crowns in cold-Winter areas. Back to Reference Library Index
