Creating a stunning sansuyu garden in outdoor plant boxes requires selecting the right plants that thrive in confined spaces while adding beauty and harmony. Sansuyu, or Cornus officinalis, is a traditional East Asian plant known for its vibrant yellow flowers and medicinal properties. To complement it, consider these ideal plants for your outdoor plant boxes:

1. Dwarf Japanese Maple (Acer palmatum) – Adds elegance with its delicate foliage and compact size, perfect for small spaces.

2. Hosta – Provides lush greenery and thrives in shaded areas, balancing the sansuyu’s brightness.

3. Heuchera (Coral Bells) – Offers colorful foliage and thrives in containers, creating visual contrast.

4. Sedum (Stonecrop) – A drought-tolerant succulent that adds texture and requires minimal care.

5. Azaleas – Compact varieties bloom beautifully alongside sansuyu, enhancing seasonal color.

For a cohesive design, mix plants with varying heights and textures. Ensure proper drainage in your plant boxes and use quality potting soil to support healthy growth. With these selections, your sansuyu garden will flourish, offering year-round appeal in even the smallest outdoor spaces.
