''Hedera colchica'' is a species of ivy (genus ''Hedera'') which is native to Near and Middle East. It is commonly called Persian ivy〔(【引用サイトリンク】publisher=BBC website )〕 or colchis ivy.〔 It is an evergreen climbing plant, growing to 30 m high where suitable surfaces (trees, cliffs, walls) are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. In warm climates, it grows more rapidly and becomes established faster than other ''Hedera'' species. ==Description== The leaves are alternate, they are of two types, with palmately five-lobed juvenile leaves on creeping and climbing stems, and unlobed cordate adult leaves, lauroid type, on fertile flowering stems exposed to full sun, usually high in the crowns of trees or the top of rock faces. Stems are green. It has the largest leaves of any ivy to 15 cm wide and 25 cm long. The flowers are produced from late summer until late autumn, individually small, greenish, produced in large numbers in umbels, and very rich in nectar, an important food source for bees and other insects. It flowers in September and fruits form during or after winter. The fruits are berries, globular and black when ripe. They are an important food for many birds. There are one to five seeds in each berry, which are dispersed by the birds swallowing the berries.〔(【引用サイトリンク】url=http://davisla.wordpress.com/2012/01/24/plant-of-the-week-hedera-colchica-dentata-variegata/ )〕 The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit: * ''H. colchica''〔(【引用サイトリンク】publisher=Royal Horticultural Society )〕 * 'Dentata', commonly called Bullock's heart ivy, or Elephant's ears.〔(【引用サイトリンク】publisher=Royal Horticultural Society )〕 * 'Dentata variegata', synonyms 'Dentata aurea', 'Variegata'〔(【引用サイトリンク】publisher=Royal Horticultural Society )〕 * 'Sulphur heart', synonym 'Paddy's pride'〔(【引用サイトリンク】publisher=Royal Horticultural Society )〕 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「Hedera colchica」の詳細全文を読む スポンサード リンク
