Why Beachy, Coastal Garden Themes Are Perfect for Summer

Coastal garden themes capture the essence of summer with their light, airy aesthetics and natural elements like driftwood, shells, and salt-tolerant plants. These designs evoke relaxation and adventure, making them ideal for warm-weather enjoyment, whether you’re hosting barbecues or unwinding in your backyard. They’re sustainable, using drought-tolerant natives and recycled materials to reduce water use (by up to 50%, per The Spruce) and maintenance costs ($50–$100/year vs. $500 for traditional lawns). Coastal gardens are also versatile, adaptable to small patios, large yards, or containers, and inclusive for beginners, families, and eco-conscious gardeners.

These themes align with summer’s carefree spirit, incorporating weathered textures, ocean-inspired colors, and low-maintenance plants that thrive in heat. By prioritizing native species and water-saving techniques, they support pollinators and local ecosystems, as noted by Garden Design. The nine themes below offer step-by-step guidance, plant recommendations, and decor ideas to create a coastal garden that feels like a seaside escape, no matter your location.
