Sedum Green Roof Trays

Transform any flat or gently sloping roof into a lush, low-maintenance green roof with our Sedum Green Roof Garden Trays, also known as Sedum cassettes. Each tray contains a diverse mix of at least eight drought-tolerant sedum species, providing instant visual impact, colour variation, and increased biodiversity. Designed for extensive green roof projects, these modular trays feature an integrated drainage layer, filter layer, lightweight substrate, and mature vegetation in one ready-to-install system.

The low-growing, hardy sedum plants are perfect for harsh, exposed environments, thriving on rooftops with minimal maintenance. Lightweight yet robust, the trays interlock easily, enabling fast installation across residential, commercial, or community buildings. Sedum Green Roof Garden Trays support sustainable urban development, helping councils, landscapers, and designers meet SuDS, Biodiversity Net Gain, and urban greening requirements.
