Globe artichokes are tender perennials that will survive winter if mulched heavily with straw. Like asparagus, globe artichokes are herbaceous perennials, all but disappearing in the winter and coming back to life in spring. They are started easily from seed indoors now, less easily found in nurseries in the spring. Jerusalem artichokes grow as tubers attached to the roots of a particular wild sunflower. Leeks are hardy, surviving winter and going to seed in the spring.
Seeds germinate quickly, and by fall a new harvest of young leeks is ready to pick.
Leave a few in the garden through winter for a continual supply. The initial effort of the permanent garden planting will be a memory in future years, but the rewards will be tangible and enduring. News Jobs AP Shopping Archives Entertain.
