The plant is suitable as a slow-growing, specimen shrub in any garden but particularly suited to small gardens, as it does not get very big and it has such a neat habit. The clusters of scented flowers and yellow to red berries are what make this tree so ornamentally decorative and enjoyable, because between the long seasons of flowering and fruiting this shrub has something to offer almost all year long. It also makes a fantastic container plant, and would also be well placed amongst boulders, or in a rockery in a hot, sunny, exposed spot (as this is closest to its natural habitat), although it will tolerate light shade and a more protected aspect. If planted in an exposed situation in a windy coastal garden, it will most likely exhibit a wonderfully gnarled trunk. It is wind-tolerant, water-wise and will tolerate drought but as with most plants, will do well with consistent, if infrequent, watering, regular composting, and an occasional feed with a high nitrogen, organic or chemical fertilizer to boost its growth.

The rock ash is easily grown from seed sown in spring. Soak the berries in water for a day and then remove the flesh to expose the seeds. Sow seed in trays filled with potting soil, river sand or a mixture of compost and river sand (1:1). Plant no deeper than 5 mm. The seed should germinate within 4 to 8 weeks. Seedlings should only be transplanted after reaching the two-leaf stage.

The rock ash can also be grown from tip or hardwood cuttings taken in spring. These cuttings can be treated with a rooting hormone to help stimulate rooting. Pot into a well-drained potting mix once the cuttings have rooted and have hardened off.
