Sandy soil can be challenging for gardening due to its quick drainage and low nutrient retention. However, certain plants thrive in these conditions, making them perfect for outdoor plant boxes. Here are some of the best options:

1. Lavender (Lavandula) – Known for its drought tolerance and fragrant blooms, lavender loves well-drained sandy soil and full sun.

2. Sedum (Stonecrop) – A succulent that thrives in sandy soil, sedum requires minimal water and adds texture to your planters.

3. Russian Sage (Perovskia atriplicifolia) – With silvery foliage and purple flowers, this hardy plant excels in sandy, dry conditions.

4. Yarrow (Achillea millefolium) – A resilient perennial that attracts pollinators and adapts well to poor, sandy soils.

5. Blanket Flower (Gaillardia) – Bright and colorful, this drought-tolerant plant blooms all summer with minimal care.

For optimal growth, mix compost into sandy soil to improve moisture retention. Choose plants that naturally adapt to arid conditions for a low-maintenance, vibrant outdoor display.
