1 packet contains Artichoke Green Globe - 10 seeds.In warm climates, artichokes are an edible perennial or biennial, usually planted in the fall for a spring harvest, and grown as an annual in colder climates. Native to the Mediterranean, artichokes provide delicious, tender thistles for eating and are also a beautiful garden feature (zones 4 to 11). Globe artichoke is an heirloom vegetable grown for its tender, edible flower buds. With their large, silvery-green leaves and thick stems topped with pinecone-like flower buds, artichoke plants add a strong architectural element to vegetable garden plantings. Artichoke plants thrive best where mild winters and cool, foggy summers prevail. In such growing conditions, they are perennials, yielding harvests for up to 5 years. Where winters dish up only a few frosty nights, plants will sometimes overwinter when pruned and mulched (zones 8 and 9). In colder regions, you have to treat artichokes as annuals planted in spring. They are best planted in fall in the humid, subtropical, frost-free areas of zones 10 and 11.
