African blue basil (''Ocimum kilimandscharicum'' × ''basilicum'' 'Dark Opal') is native to Kenya, Tanzania, Uganda, Sudan, and Ethiopia.〔(Kew World Checklist of Selected Plant Families )〕 It is one of a few types of basil that is perennial. It is a sterile hybrid of two other breeds of basil, unable to produce seeds of its own, and is propagated by cuttings. ''Ocimum kilimandscharicum'' has a strong camphor scent, inherited from ''Ocimum kilimandscharicum'' (camphor basil),〔(【引用サイトリンク】 url = http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?25484 ) Gives as its source ''Econ Bot'' 28:63 (1974).〕 its East African parent.〔 The concentration of camphor is 22% (compared with 61% for ''O. kilimandscharicum''). The concentration of the other major aroma compounds, linalool (55%), and 1,8-cineole (15%) is comparable to many basil cultivars.〔, ("Basil: A Source of Aroma Compounds and a Popular Culinary and Ornamental Herb" ), reprinted from: ''Perspectives on new crops and new uses'' (1999), ASHS Press, Alexandria, VA, ISBN 978-0-9615027-0-6.〕 It has similarities to both Thai and sweet basil, yet has a flavor all its own. Its long, pink flowers also make a striking garnish. Although not yet widely known as a useful culinary herb, it shows potential for wider popularity. When added to a dish, it can taste like more than one herb has been used. The leaves of African blue basil start out purple when young, only growing green as the given leaf grows to its full size, and even then retaining purple veins. Based on other purple basils, the color is from anthocyanins, especially cyanidin-3-(di-p-coumarylglucoside)-5-glucoside, but also other cyanidin-based and peonidin-based compounds.〔 It blooms profusely like an annual, but being sterile can never go to seed. It is also taller than many basil cultivars. These blooms are very good at attracting bees and other pollinators. ==See also== * List of basil cultivars 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「African blue basil」の詳細全文を読む スポンサード リンク
