Why build a living wall or green roof
Green walls and green roofs can easily be installed into existing spaces and infrastructure.
benefits of a green wall
- They reduce the negative impact of storm-water run-off, which carry loads of pollutants into our freshwater streams and into the oceans
- provide an urban sponge to reduce flooding,
- reduce the heat island effect that occurs in city scapes where there are lots of tarseal and dark plain surfaces,
- provide habitats for plants and mosses to grow and small creatures such as Geckos to live, -enhance conservation efforts in an urban landscape when native plants are selected
- are aesthetically beautiful and calming.

Native Plants from the rocky outcrop regions
The rocky outcrops of banks peninsula are home to an amazing diversity of life (see some of the plants below). Our first living wall brings that biodiversity to the city.
The windy sun-baked site on the corner of Cashel street and High street is not unlike the harsh conditions of rocky outcrops that survive in a harsh, windy and dry environment.
The rocky outcrops support a larger number of species. They are like a refuge, as there is not enough vegetation to take a fire up the rock faces. They manage to avoid grazing animals and disturbances from people because of their difficulty to access. Moreover, they are a refuge because many of the species on rocky outcrops once lived in other places at lower elevations.
The North facing crops are prone to drought stress, and are different to the Southern facing plants that have more moisture.
Rocky outcrop plants are unusual, as they survive in extreme weather conditions due to their exposure and rocky environment that only provides small pockets of soil and water deep below.
