Perennial vegetables are parts of plants that are prepared and eaten like a vegetable, and that are also perennial, in other words, the plants live for more than two years. Some well known perennial vegetables from the temperate regions of the world include asparagus, artichoke and rhubarb. In the tropics cassava and taro are grown as vegetables, and these plants can live many years. Perennial vegetables are an integral part of many cultural diets around the world, particularly in tropical agriculture. Perennial vegetables fell out of favor in most of Europe, and other western influenced cultures, once industrial agriculture gained a foothold.〔C. Picone and D. Van Tassel. 2002. (Agriculture and Biodiversity Loss: Industrial Agriculture ). The Land Institute〕 Some of the older temperate varieties include: seakale, skirret, sorrel, and Good King Henry. These plants are an integral part of any successful forest garden, being incorporated into both the herbaceous layer (like a ground cover), or even low growing canopy layer (like overstory trees and shrubs). == List == * Abelmoschus manihot, edible hibiscus * Allium ampeloprasum, perennial leek * Allium cepa aggregatum, potato onion * Allium × proliferum, tree onion or walking onion * Aralia cordata, udo * Arracacia xanthorrhiza, arracacha * Artocarpus altilis, breadfruit * Asparagus officinalis, asparagus * Atriplex halimus, saltbush * Basella alba, Malabar spinach * Beta vulgaris maritima, sea beet * Blitum bonus-henricus, Good King Henry * Brassica oleracea acephala varieties, tree collards or tree kale * Brassica oleracea alboglabra, kai-lan * Bunias orientalis, Turkish rocket * Camassia spp., camas * Canna edulis, achira * Capsicum baccatum, aji amarillo * Capsicum pubescens, manzano chile * Carica papaya, papaya * Cicorium intybus, chicory * Cnidoscolus chayamansa, chaya * Coccinia grandis, ivy gourd or perennial cucumber * Colocasia esculenta, taro * Crambe maritima, sea kale * Cynara scolymus, artichoke * Dioscorea bulbifera, air potato * Ipomoea batatas, sweet potato * Lablab purpureus, hyacinth bean * Manihot esculenta, cassava * Nelumbo nucifera, lotus * Oxalis tuberosa, oca * Phaseolus coccineus, runner bean * Rheum rhabarbarum, rhubarb * Rumex acetosa, sorrel * Rumex scutatus, shield-leaf sorrel * Sauropus androgynus, katuk * Sium sisarum, skirret * Suaeda pulvinata, seepweed * Toona sinensis, fragrant spring tree or xiāngchūn * Vasconcellea × heilbornii, babaco papaya 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Perennial vegetable」の詳細全文を読む スポンサード リンク
