How to Grow a Marble Queen Plant
Native to Australia and New Zealand, marble queen plants (Coprosma repens) are suitable for growing in USDA plant hardiness zones 9 and up. They work well as hedges or windbreaks, along borders, or in woodland gardens. This plant tolerates wind and salt spray, making it a great choice for coastal areas. However, the plant may struggle in hot, dry climates.
Marble queen plants are often available at nurseries and garden centers in appropriate climates. You can also take softwood cuttings from a mature plant when the plant is putting on new growth in spring or summer, or by semi-hardwood cuttings after flowering.
Male and female plants are on separate plants, so plant both in close proximity if you want tiny yellow blooms in summer and attractive berries in fall. Allow 6 to 8 feet (2-2.5 m.) between plants.
They perform best in full sun or partial shade. Most well-drained soils are appropriate.
Marble Queen Plant Care
Water the plant regularly, especially during hot, dry weather, but be careful not to overwater. Marble queen plants are relatively drought tolerant, but don’t allow the soil to become totally dry.
Apply 2 to 3 inches (5-8 cm.) of compost, bark or other organic mulch around the plant to keep the soil moist and cool.
Prune errant growth to keep the plant neat and shapely. Marble queen plants tend to be pest and disease tolerant.
