Botanical Name: Aucuba japonica 'Variegata'
Green leaves heavily dusted with golden-yellow spots makes Gold Dust Plant a cheery house plant, and a beautiful accent among other foliage plants.
You'll have easy success with this compact, upright shrub because it adapts well to indoor conditions.
In fact, it doesn't need much attention to thrive. It grows well in a pot. Just shade it from direct sunlight, keep it cool and well-watered. Prune it back each spring to keep it small.
Aucuba japonica varieties include both male and female plants that produce clusters of tiny purplish flowers in spring. They're not very attractive, but if pollinated, the flowers are followed by bright red berries carried on the plant through the winter.
Prune in spring. Although slow-growing, Gold Dust Plants will get tall and leggy over time. Prune the stems back hard in spring to keep Japanese aucuba a manageable size indoors and to encourage branching.
Pruning tip: Cut stems at a 45° angle, just above a node (the place where a leaf or branch is attached to the stem). Use sharp pruners to avoid tearing the stems.
Repot in spring, moving up to a container 1 size larger every 2-3 years, or when needed. If your Japanese aucuba is already big, you can top-dress instead by removing the top 2-3 (5-7.5 cm) inches of soil and replace it with fresh potting soil.
Clean those beautiful spotted leaves to keep them dust-free. Wipe them off with a damp cloth.
