''Gunnera tinctoria'', known as giant-rhubarb or Chilean rhubarb, is a plant species native to southern Chile and neighbouring zones in Argentina. It is essentially unrelated to rhubarb, as the two plants belong into different orders, but looks similar from a distance and has similar culinary uses. It is a large-leaved perennial plant that grows to more than two metres tall. It has been introduced to many parts of the world as an ornamental and edible plant. In some countries (for instance New Zealand and Ireland) it has spread from gardens and is becoming a weed problem. It is known under the synonyms: * ''Gunnera chilensis'' Lam. * ''Gunnera scabra'' Ruiz & Pav. ==Description== ''Gunnera tinctoria'' is a giant, clump-forming herbaceous perennial. The leaves can grow up to 2.5m across. It has erect spikes of cone-shaped inflorescences (to 1m) from spring to early summer, with small flowers. The fruit is orange. The number of seeds is estimated from 80,000 per seedhead to 250,000 per plant. 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「Gunnera tinctoria」の詳細全文を読む スポンサード リンク
