If you're considering growing a small edgeworthia in an outdoor plant box, the answer is yes—with the right care. Edgeworthia, also known as paperbush, is a charming flowering shrub that thrives in well-draining soil and partial shade. Here’s what you need to know to ensure success:

1. Choose the Right Box: Opt for a sturdy, spacious plant box with drainage holes to prevent waterlogging. Edgeworthia’s roots need room to spread.

2. Soil Requirements: Use a mix of loamy soil and organic compost to mimic its natural habitat. Good drainage is crucial to avoid root rot.

3. Light and Location: Place the box in a spot with dappled sunlight or morning sun. Too much direct afternoon sun can scorch the leaves.

4. Watering Needs: Keep the soil consistently moist but not soggy. Edgeworthia prefers humidity, so misting can help in dry climates.

5. Winter Care: In colder zones, protect the plant box from freezing temperatures by moving it to a sheltered area or insulating it.

With proper attention, your edgeworthia can flourish in an outdoor plant box, adding unique beauty to your garden or patio. Happy gardening!
