Ipomoea carnea

Ipomoea carnea, commonly the pink morning glory or bush morning glory, is a branched, erect, shrublet, an exotic. In some parts of the world it may grow from 1 m to 3 m tall.

The narrowly heart-shaped leaves with entire margins fold in slightly along their midribs and are conspicuously veined. The leaves become up to 23 cm long.

The species is introduced and established in the veld in the northeastern parts of South Africa, also found in tropical and temperate areas in North and South America and Asia; probably originating from Argentina.

The seeds that grow easily and the leaves are toxic to cattle. The plant is used in making paper and in traditional medicine. The hollow stems are used to make pipe-stems in Brazil.

There are two subspecies, viz. subsp. fistulosa and subsp. carnea (Wikipedia; iNaturalist).
