The rooftop garden captures rain events, and manages water through several processes. Plants capture and store water for use in dry periods. Water is stored in the growing medium, and wicking action alone releases rain into the air after a rain event. During the growing season, evapo-transpiration by plants releases stored rain into the air.

A mix of native and non-native species were planted that have a variety of adaptations. The high diversity of plants forms a community that is adaptable to a variety of weather patterns from moist spring weather to long summer droughts.

The following plants have been planted on our roof:

• Sedum reflexum
  Blue Spruce Stonecrop
• Sedum spurium
  Red Stonecrop
• Sedum kamtchaticum
  Russian Stonecrop
• Sedum sexangulare
  Six-angled Stonecrop
• Sedum pulchellum
  Annual Stonecrop
• Sedum ternatum
  Appalachian Stonecrop
• Tradescantia ohioensis

Ohio Spiderwort

Once the green roof is fully saturated, excess water is directed by the roof drain to the rain garden below for the next chain of water management.

Apart from alternate water options, our green roof provides a multitude of benefits for the building as well as the city including increased air quality, greater biodiversity and energy conservation. For more information on our green roof visit https://www.restorationgardens.ca/
