Plant Profile: Aucuba japonica

Aucuba japonica, belonging to the Garryaceae family (previously classified under Cornaceae), is commonly known as spotted laurel. This evergreen shrub is characterized by its rounded, dense, and upright form, thriving in shady environments and boasting strikingly variegated leaves. It flourishes in soils rich in organic matter that remain consistently moist, ideally in partial to full shade, though it can adapt to poorer soils and urban settings, including areas with air pollution. Typically, it reaches heights of 6 to 10 feet, occasionally growing up to 15 feet if not pruned.

Plants of this species are dioecious, meaning that male and female flowers are found on separate specimens. When female plants are situated near males, they produce vibrant red fruits in winter, adding visual interest throughout the year.

Aucuba japonica is easy to transplant and can be propagated from seeds or stem cuttings. In temperate regions, it is often cultivated as a houseplant, thriving in cooler indoor temperatures ranging from 50 to 65 degrees Fahrenheit.

The plant flowers in early spring, showcasing glossy foliage, and is frequently used as a potted plant in northern climates.

In terms of pests and diseases, indoor specimens may be affected by spider mites, while outdoor varieties can encounter issues with scale, nematodes, and mealybugs. Fungal leaf spots and southern blight may also occur, and overly wet soils can lead to root rot. Additionally, the foliage is vulnerable to windburn and sun-scald, so it is advisable to plant it in a sheltered location.
