We love our green roofs. Every roof area of our building is either covered in plants or solar cells. We have used some grasses but also lots of sedums and some cactus. Some of our roofs are visible to the public and have been made into very pretty gardens with iris, blazing star, a variety of tall, ornamental grasses, sedums with showy flowers and sedums with colorful leaves, and a wide variety of native forbs and flowers. There is also a small, shallow "pond" on this roof that, in combination with a hidden reservoir, stores rain water to water the plants here. The other roofs are less ornamental and store rainwater in the soil. Here is a link that we are still developing that shows some of the roofs (it refreshes every 30 seconds). http://greenback.chias.org/demo.html Some of the plantings on these roofs are new last season so still have a lot of growing to do. Unfortunately, the most mature and prettiest ones don't have cameras because you can see them live. Although we haven't had any real problems with the roofs and it doesn't seem like we ever will, be sure everything under them is secure when they test the membrane seal. After installation of the waterproof membrane, they flood the area and look for leaks. If there is one you will know because it will start draining into the galleries. Steven M.
