Yes, you can successfully grow a small sarcococca in an outdoor plant box, provided you meet its basic growing conditions. Sarcococca, also known as sweet box, is a hardy evergreen shrub that thrives in partial to full shade, making it ideal for balconies, patios, or shaded garden spaces.

When planting sarcococca in a plant box, ensure the container has adequate drainage to prevent waterlogging. Use well-draining, humus-rich soil and place the box in a sheltered spot to protect it from harsh winds. Water regularly to keep the soil moist but not soggy, especially during dry spells.

Sarcococca is low-maintenance and rewards gardeners with fragrant winter blooms and glossy foliage. With proper care, your outdoor plant box can become a charming home for this delightful shrub.
