Ipomoea calobra, commonly known as weir vine, is an Australian native plant[2] found in northern Australia, largely Western Australia and Queensland.[3]
It is a climber growing up to 6 m high, with purple-blue-pink trumpet flowers from January to June.[2]
It occurs on undulating plains, dunes, and hardpans in red sandy and clayey soils, and pebbly loam,[2] and is often found twined up mulga and other acacias.[4]
The tubers of this species are edible, and were a highly favoured staple food source (bush tucker) for Indigenous Australians.[4] The mature tubers are broadly similar nutritionally to sweet potato (Ipomoea batatas), with higher concentrations of starch, potassium (K), copper (Cu) and zinc (Zn).[5]
In some parts of Australia, I. calobra is also known to Aboriginal people by the following names:[5]
