Ipomoea costata |
Ipomoea costata, commonly known as rock morning glory, is an Australian native plant.[2] It is found in northern Australia, from Western Australia, through the Northern Territory, to Queensland.[3] Its tubers provide a form of bush tucker to some Aboriginal peoples, known as bush potato,[4] or (to the Ngururrpa groups in WA), karnti.[5]
Description
[edit]It is a prostrate or climbing perennial growing up to 3 m high, with purple-blue-pink flowers from February to November.[2] Juvenile form is a vine, maturing into a woody-stemmed shrub with vine-like stems. Leaves are broad and leathery, 4-9 cm long.[4] Tubers are rounded, 12-20 cm long by 5-18 cm wide, with a single plant potentially having up to twenty tubers.[6]
Habitat
[edit]It occurs on sandy or rocky soils, often over limestone,[2] and on spinifex sand plains in northern Australia.[4]
