The GARDENA NatureUp! Vertical Set is a flexible and easily expandable system that allows you to green walls with flowers, vegetables, and aromatic plants quickly and effortlessly. The weather-resistant plastic planters connect easily to each other without difficulty and can be mounted on the wall or placed on the floor. Integrated drainage in each planter prevents the accumulation of excess moisture, while surplus water is collected in the base tray, keeping walls and floors clean.
