A well-known Mexican plant with fleshy trailing stems and oval-oblong leaves, purple beneath, but striped with greenish-white above. There is a fine form having the leaves striped with yellowish-white and suffused with carmine rose, and another striped with bright yellow. There is also one having wholly green leaves hardier than the coloured forms. All kinds are easily raised from cuttings, and may be grown in the greenhouse or stove. They are useful for edgings and hanging baskets, indoor rookeries, etc, and grow in any light soil.
