Arranging druid garden plants in an outdoor plant box requires a blend of practicality and creativity. Start by selecting plants that thrive in your climate and complement each other in terms of height, color, and growth habits. Taller plants like foxgloves or hollyhocks should be placed at the back, while medium-height herbs such as sage or thyme can occupy the middle. Low-growing plants like creeping thyme or moss work well at the front.

Ensure proper spacing to avoid overcrowding, which can lead to poor air circulation and disease. A good rule is to leave at least 6-12 inches between plants, depending on their mature size. Incorporate a mix of textures and colors to create visual interest—think silvery foliage paired with vibrant blooms.

For a druid-inspired touch, consider adding symbolic plants like oak seedlings or mistletoe. Finally, mulch the soil to retain moisture and suppress weeds. With thoughtful arrangement, your outdoor plant box will become a thriving, magical garden space.
