A species of morning glory, it has many common names, including mile-a-minute vine, Messina creeper, Cairo morning glory, coast morning glory and railroad creeper. The species name cairica translates to "from Cairo", the city where this species was first collected.

How to grow it

Some plant nurseries sell this plant as an ornamental plant thanks to its showy purple flowers and as well for its fast growth to quickly cover unsightly fences or walls. It can grow as a separate plant if snapped during attempted removal process. The plant causes respiratory symptoms if ingested.

Ipomoea cairica 'alba', also known as 'white Cairo morning glory', is a variety with white flowers.

Where it grows

Its exact native range is uncertain, though it is believed to originate from a rather wide area, ranging from Cape Verde to the Arabian Peninsula, including northern Africa, tropical Africa and the Mediterranean. It covers walls, fences or trees, with stems that can measure more than 10 metres (33 ft) in length. The altitude at which it has been recorded ranges from 250 metres (820 ft) to 2,250 m (7,380 ft).

Uses

Most parts of the plant are edible. Its roots are reportedly edible when cooked and its leaves are eaten when young.
