If you're considering growing a small daphne in an outdoor plant box, the answer is yes—with a few important considerations. Daphne shrubs, known for their fragrant blooms, thrive in well-draining soil and partial shade, making them suitable for container gardening.

Key Factors for Success:

1. Drainage: Ensure your plant box has adequate drainage holes to prevent root rot.

2. Soil: Use a slightly acidic, loamy mix to mimic daphne's natural habitat.

3. Sunlight: Place the box in dappled sunlight or morning sun with afternoon shade.

4. Size: Choose a box at least 12-16 inches deep to accommodate root growth.

Daphnes are sensitive to overwatering and extreme temperatures, so monitor moisture levels closely. With proper care, your outdoor plant box can become a charming home for this fragrant, evergreen shrub.
