Ipomoea costata is a prostrate scrambling vine with heart shaped leaves and funnel shaped rose-purple flowers with a darker throat. Native to sandy arid parts of Northern Australia (NT and WA). Closely related to the sweet potato and produces large, tasty tubers.
Many members of the Convolvulaceae family are used shamanically, medicinally and for divination purposes (for example, Rivea corymbosa, Stictocardia tiliifolia and Ipomoea violacea). Ipomoea batatas (Sweet Potato) is a family member used for food production. I. costata is a native whose tubers were an important food source for Aborigines.
Care and Cultivation
Seeds should be slightly nicked away from the embryo and soaked in water overnight to speed germination. Likes adequate water and a full-sun to part-shade position in well drained soil. Quite tolerant of dry and hot conditions. Grows in sandy and clayey soils of inland Australia.
