Full Description

The Cubrosa 85cm planter is a bold yet refined solution for serious garden design. With its clean lines and impressive scale, it’s ideal for creating structured visual zones or anchoring large green elements in residential or commercial outdoor spaces. Its true cube form complements everything from modern paving to natural stonework, adding crisp definition to any setting.

Each Cubrosa is cast in high-grade pigmented cement stone — not painted — meaning the colour penetrates the entire form for long-lasting integrity. The White Mist shade combines pale white and light grey hues, making it ideal for bright, clean landscaping styles or indoor environments that favour a minimalist tone.

Weighing 111kg, this planter offers unrivalled security and stability for windy areas or public spaces, yet is refined enough for upscale settings. The internal seal and drainage system ensure optimal plant health, while the flat base allows effortless placement on patios, roof terraces, or entranceways.

Perfect for housing trees, topiary, bamboo, or sculptural grasses, the Cubrosa 85cm brings both substance and sophistication to any design scheme. Whether used solo or in a group, it elevates the look and longevity of any planting project.
