Native title of the NBS intervention
Portsmouth Water Drought Garden
Short description of the intervention
The drought-tolerant garden was established by Portsmouth Water at its Head Office entrance in 2007. The plants in the garden, all of which require little or no watering, were chosen to be visually stimulating whilst contributing colour, scent and variation in leaf texture and shape (1). This garden has been designed to be drought-tolerant, easily maintained and can take some wear and tear. The planting reflects the changing seasons with something of interest all year. None of the plants is difficult to grow and is easily obtainable (2).
