New Zealand Morning Glory



Botanical name:  Ipomoea cairica
Maori name:  Powhiwhi
Common name:  Coastal morning glory
Ipomea CairicaCoastal morning glory is an indigenous vine with prostrate, often twining stems up to four metres or more long. It is recognised by its mauve funnel-shaped flowers with deep purple centres. Tiritiri Matangi also has a colony of white flowering plants along the clifftops of Fisherman's Bay.The leaves are divided into 5-7 pointed lobes, each lobe 3-5cm long.

The genus Ipomoea contains about 450 species which are twining, climbing plants found in tropical and subtropical regions. This one is common throughout the tropics and sub-tropics, and Tiritiri is considered to be the southernmost limit if its natural range.

Two species of Ipomoea are important food crops:

1. Sweet potato (kumara) Ipomoea batatas, originally from South America.
Note: batata is from the Taino dialect (pre-Columbian people of Central America) and became 'patata' in Spanish and subsequently 'potato' in English.

2. Water spinach (ong choy) Ipomoea aquatica, which is grown as a leaf vegetable and is widely used in Malay and Chinese cuisine. 

'Ipomoea' means worm-like, describing its growth habit. It belongs in the convolvulus family.
