Mesembryanthemum cordifolium formerly known as Aptenia cordifolia is a species of succulent plant in the iceplant family. The common names of the plant include baby sun rose,.[1] heart-leaf,[2] red aptenia[1] or aptenia[2] in English, as well as rooi brakvygie[1] or brakvygie[1][2] in Afrikaans, and umjuluka,[2][disputed (for: source possibly mistaken, umjuluka is word for Casearia gladiiformis) – discuss] ibohlololo,[1] or uncolozi omncane[1] in isiZulu in South Africa. It is known as heartleaf iceplant in the USA[3] British names may be heart-leaved aptenia[citation needed] or heart-leaved midday flower because, like many other representatives of the Aizoaceae, it opens its flowers only during the sunshine of the day. It is a creeping plant that forms a carpet of flat-growing perennial herbs in groups on the ground from a base.[4] Genus name means middle-embryo flower in reference to the position of the ovary in the flower. The specific epithet is derived from Latin for heart-shaped leaves
