Ipomoea calobra

Ipomoea calobra, commonly known as weir vine, is an Australian native plant [2] found in northern Australia, largely Western Australia and Queensland. [3]

Contents

Description

It is a climber growing up to 6 m high, with purple-blue-pink trumpet flowers from January to June. [2]

Habitat

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]

Uses

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]

Aboriginal names

In some parts of Australia, I. calobra is also known to Aboriginal people by the following names: [5]

<span class="mw-page-title-main">Sweet potato</span> Species of edible plant

The sweet potato or sweetpotato is a dicotyledonous plant that belongs to the bindweed or morning glory family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as greens. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato, both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is not a true yam, which are monocots in the order Dioscoreales.
