Finding the right plants for dry shade in outdoor plant boxes can be challenging, but several resilient species thrive in these conditions. Here are some top choices:

1. Hostas – Known for their lush foliage, hostas adapt well to shade and require minimal watering once established.

2. Heuchera (Coral Bells) – With vibrant leaves and tolerance for dry shade, these perennials add color to plant boxes.

3. Ferns (e.g., Dryopteris) – Many fern varieties flourish in shady, low-moisture environments, offering elegant texture.

4. Lamium (Dead Nettle) – A ground cover with silvery leaves and small flowers, ideal for dry shade containers.

5. Epimedium (Barrenwort) – Drought-tolerant and shade-loving, this plant provides delicate blooms and foliage.

For best results, use well-draining soil and mulch to retain moisture. These plants not only survive but also enhance shaded outdoor spaces with minimal care.
