What are the cost differences between stone, granite, marble, and concrete outdoor flower boxes?

When choosing outdoor flower boxes, material cost is a key factor. Stone flower boxes are durable but can be expensive, ranging from $200 to $800 depending on the type of stone. Granite flower boxes are premium options, costing $300 to $1,000 due to their strength and aesthetic appeal. Marble flower boxes are elegant but pricier, averaging $400 to $1,200, and require more maintenance. Concrete flower boxes are the most affordable, typically $50 to $300, offering durability at a lower cost. Consider your budget and design preferences when selecting the best material for your outdoor space.
