Ipomoea nil is a species pf Ipomoea morning glory known by the common name Japanese morning glory (although it is not native to Japan). It is native to the tropical Americas, and has been introduced widely across the world. Native to Central America and Mexico, the plant is a climber with twining stems up to 5 m long and is dense to scattered with long hairy trichomes. The finely hairy, emerald green leaves are ovate to almost circular, 5 to 14 cm long. The base is heart-shaped, the edge is entire or lobed three to five times, the leaf lobes are pointed or tapering. The funnel-shaped, colorful flowers (blue to reddish-purple, with whitish tube) are quite showy and are individually up to five in often dense cymose groups, in which fully developed flowers and developing buds stand together.

Description

• Ipomoea nil, commonly known as ivy-leaved morning-glory or Japanese morning-glory, is a fast-growing annual climbing vine in the morning-glory family (Convolvulaceae). Its twining stems are covered with long, stiff hairs, and its broadly ovate, hairy leaves have heart-shaped bases and may be entire or divided into three to five pointed lobes. The showy, funnel-shaped flowers are usually blue, purple, or reddish-purple, sometimes with a white throat, and open in the morning before closing later in the day. The fruit is a rounded capsule containing dark, hairy seeds.

Range

• Ipomoea nil is native to Mexico and tropical regions of the Americas, including Central America, the Caribbean, and parts of South America. It has been introduced and cultivated widely around the world as an ornamental plant. It is native to Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• It grows in thickets, grasslands, woodland margins, roadsides, cultivated fields, and disturbed areas. It favours warm conditions, sunny locations, and well-drained soils, climbing over shrubs, fences, and other vegetation. It can also escape from gardens and establish in secondary vegetation.
