An 8 story green roof and rooftop garden

We finished a green roof in downtown Toronto in mid-August. It is doing well, here are a few photos of the installation; from the rooftop (the eighth story) you can see Lake Ontario.

At about 2000 square feet, it features planter boxes with 15 inches of medium for the residents to plant in and a conventional green roof filled with native wildflowers, native grasses, a few trusty sedum species and roseroot, a first on a green roof...as far as I can tell!
