What are the best stone types for constructing an outdoor flower box?

When designing an outdoor flower box, choosing the right stone type is crucial for durability and aesthetics. Natural stones like granite, limestone, and sandstone are excellent options due to their weather-resistant properties and timeless appeal. Granite is highly durable and can withstand harsh weather conditions, making it ideal for long-lasting flower boxes. Limestone offers a softer, elegant look but requires sealing to prevent water damage. Sandstone, with its natural texture and variety of colors, adds a rustic charm to garden designs. For a modern touch, consider using slate, which is lightweight and resistant to cracking. Each stone type has unique characteristics, so select one that complements your garden's style while ensuring longevity and functionality.
