Ipomoea nil is a species of Ipomoea morning glory known by several common names, including picotee morning glory, ivy morning glory, and Japanese morning glory. It is native to most of the tropical world, and has been introduced widely.
Cultivation[edit]
It is cultivated as an attractive ornamental plant in many places, and the descendants of garden escapees now grow wild. This is a climbing annual herb with three-pointed leaves 3 to 8 centimeters long. The flowers are several centimeters wide and appear in various shades of blue, pink or rose, often with white stripes or edges or blends of colors. Common cultivars include 'Scarlet O'Hara', 'Early Call', and 'Rose Silk'. [1][2]
Hybrids, for instance with I. purpurea, have been developed. Some of these have been given the name I. x imperialis (Imperial Japanese morning glory), which is not official. Cultivars include 'Sunrise Serenade'. Alternative nomenclatures include Ipomoea nil x imperialis, as in 'Cameo Elegance', or Ipomoea nil cv. 'Imperialis'. [3]
