Window Boxes: A Brief History and Why GRP Is the Modern Upgrade

Window boxes have been a staple of home gardening for centuries. From simple wooden troughs to ornate cast iron planters, these modest containers have added life and colour to buildings across Europe and beyond. But how did they become such a key part of our gardens—and what’s the smartest option today?

The Roots of Window Boxes

The concept of growing plants in containers dates back thousands of years. Ancient Egyptians and Romans used terracotta pots to grow herbs and ornamental plants. But the window box as we know it is thought to have first gained popularity in Italy during the Renaissance.

Urban dwellers, with limited space, needed a way to bring greenery to their homes. Small balconies and windowsills were the perfect spot—and window boxes allowed herbs, flowers, and even small vegetables to thrive above busy streets.

By the 17th and 18th centuries, window boxes had spread across Europe, becoming especially popular in densely packed cities like Paris, London, and Amsterdam. They were both decorative and practical: a burst of colour and a way to grow useful plants in tight quarters.

In Victorian Britain, window boxes became part of the iconic look of terraced houses, often filled with geraniums, ferns, and ivy. For many, they symbolised a connection to nature—a patch of garden even in the heart of a city.

Modern Window Boxes: What’s Changed?

While the concept hasn’t changed, materials and design have evolved dramatically. Traditional wooden boxes, while charming, suffer from rot, warping, and cracking over time. Metal boxes can rust, and terracotta—while beautiful—can crack in frost.

This is where modern materials like GRP (Glass Reinforced Plastic) have transformed the market.
