Gardening in sandy soil can be challenging due to its quick drainage and low nutrient retention. However, choosing the right plants for an outdoor plant box in sandy conditions can lead to a thriving, low-maintenance garden. Here are some of the best plants suited for sandy soil:

1. Lavender (Lavandula) – This drought-tolerant perennial thrives in sandy soil and full sun, offering fragrant blooms and attracting pollinators.

2. Sedum (Stonecrop) – A hardy succulent that requires minimal water and thrives in poor, sandy soils, perfect for sunny plant boxes.

3. Russian Sage (Perovskia atriplicifolia) – With silvery foliage and purple flowers, this plant loves dry, sandy conditions and full sun.

4. Yarrow (Achillea millefolium) – Known for its feathery foliage and bright flowers, yarrow is highly adaptable to sandy soils.

5. Beach Grass (Ammophila breviligulata) – Ideal for stabilizing sandy soil, this grass is both decorative and functional.

For best results, amend sandy soil with organic matter to improve moisture retention. Pair these plants with a well-draining outdoor plant box, and enjoy a vibrant, low-maintenance garden!
