Our Annex Garden

videos

Welcome to our demonstration garden here in front of the Annex Building at our Headquarters. It is open and meant for public view. We replaced water-intensive lawn with drought-tolerant landscape that attracts birds and insects. The garden includes these sustainable elements:





Xeriscape: Drought-tolerant landscaping conserves water, especially in drought conditions. Selected plants and succulents replace thirsty grass and provide for an attractive alternative landscape. No more mowing the lawn.





Bioswale: A bioswale demonstrates how to draw stormwater run-off into the ground, instead of washing onto to the street where it drags motor oil/fluids to the sea. It consists of a thick pervious layer of rocks which holds water and acts as a conduit to the soil beneath.





Raised-beds: Two raised-beds showcase growing local organic food. Part of a closed-loop system that produces herbs and vegetables for consumption in our cafeteria on premises, which then composts discarded food waste in worm bins. The worm castings and tea created then fertilize the garden.




Wildlife: Planted fauna attracts a biodiverse array of birds and insects. This includes the Monarch Butterfly which has been in decline due to climate change issues. Selected plants invite hummingbirds and bees to feed on the nectar.

The xeriscape is divided into different zones:




Drought-tolerants: In the mulched areas are bright and attractive drought-tolerant plants, which draw in butterflies, bees and hummingbirds.

Succulents: In the sloped dirt areas are vibrant succulents that require miniscule water.
