About

Ipomoea indica is a species of flowering plant in the family Convolvulaceae, known by several common names, including blue morning glory, oceanblue morning glory, koali awa, and blue dawn flower. It bears heart-shaped or three-lobed leaves and purple or blue funnel-shaped flowers 6–8 cm (2–3 in) in diameter, from spring to autumn. The flowers produced by the plant are hermaphroditic. This plant has gained the Royal Horticultural Society's Award of Garden Merit.

The plant is grown as an ornamental for its attractive flowers, but is considered invasive in many regions of the world, being specifically listed on New Zealand's Biosecurity Act 1993.

How to grow it

Blue morning glory is a popular species widely cultivated as an ornamental plant for its colourful flowers. It has spread throughout the tropics and subtropics of the Old World although those regions are not part of its native range. As it does not tolerate temperatures below 7 °C (45 °F), in temperate regions it is grown under glass. It likes very light and nutrient-rich soil, which should be kept evenly moist.

Where it grows

Its exact native distribution is unclear due to it being widely cultivated throughout the tropics of Eurasia, Africa and America, but it is currently thought by most authorities to be native to the Neotropics, from Florida in the United States south to Mexico, Central America, and the Caribbean and south to South America. It is also considered native to several Pacific islands, including Palau, the Hawaiian Archipelago (where its native Hawaiian name is Koali ‘awa), French Polynesia, and Micronesia.
