The Story
Plant Bio
Skimmia japonica, the Japanese skimmia, is a slow-growing, broadleaf evergreen shrub native to the forested regions of Asia. It forms a dense, rounded dome of leathery, glossy dark green leaves that release a spicy aroma when crushed.
'Rubella' is a distinct male clone selected for its prominent, deep red flower buds that persist throughout fall and winter before opening into fragrant, creamy-white spring blooms. Because this selection is strictly male, it does not produce berries, but it serves as an exceptional pollinator for female cultivars.

Planting
How to Grow
- Select a planting site in partial to full shade with moist, organically rich, acidic soil.
- Dig a hole twice the width of the root ball and backfill with compost to ensure excellent drainage.
- Set the plant at the same depth as it was in the container, avoiding burying the crown.
- Water thoroughly and apply an organic mulch to retain consistent soil moisture.
Pro Tip
Plant in acidic, humus-rich soil in partial to full shade; full sun bleaches the evergreen foliage, while alkaline soils trigger severe iron chlorosis.

Care Guide
Do
- Do plant in dappled or afternoon shade to prevent leaf scorch.
- Do mulch annually with compost or ericaceous matter to maintain soil acidity.
- Do ensure sharp drainage to prevent root rot.
Don't
- Don't plant in high-pH alkaline or chalky soils.
- Don't prune hard into old, leafless wood as it will not resprout.
- Don't allow the soil to dry out completely.
