Botanical name: Aptenia cordifolia
Common name: Baby Sun Rose
Family: Aizoaceae
Origin: South Africa
This plant grows best in full sun and tolerates poor soils, heavy or well-drained. Flowering is in summer and autumn. Easily propagated by cuttings or seed. The very similar A. lancifolia, sometimes refered to in the trade as A. cordifolia 'Fuchsia', is almost identical (the leaves are less cordate) except in being less vigorous, and with distinct magenta or fuchsia colored flowers.
They grow well on retaining walls and hanging baskets.
