Are vegetated roofs necessarily green in color?
No! Many vegetated roofs appear red, orange, yellow and all colors in between at different times of the year because the fleshy leaves of various succulents change colors throughout the year. Also, vegetated roof plants are not all evergreen, nor should they be. The beauty and anticipation of the change of seasons add to the color palette. And of course, flowers vary, too, in colors from whites to yellow, pinks, deep reds and purples and blues. A virtual living carpet or tapestry varies from season to season as plant communities naturally migrate in their random regenerative patterns.
