How to Grow

Cultivation

Grow in pots of peat-free, loam-based compost with added extra grit. Position in a sunny spot for the best leaf colouration; aeonium will tolerate some shade but the leaves become green. Water moderately when in growth, not at all when dormant. Apply a balanced liquid fertiliser 2 or 3 times during the growing season. In winter move plants to a frost-free greenhouse or conservatory. See hardy cacti and succulent cultivation for further information

Propagation

Propagate by seed sown at 19-24ºC in spring or by cuttings of rosettes kept at 18ºC and barely moist until rooted
