Did you know a Green Roof and a Roof Garden are two different things? The difference between a green roof and a roof garden is their primary function. A roof garden is just that, a garden on the roof; and it’s made up of garden planters, flower boxes, potted trees and shrubs, annuals, perennials, and even vegetables. The garden is many times planted on the roof because of a need for space to garden, especially for urban gardeners. A green roof is a roof covered with a certain growing medium and specific plants such as mosses and sedums that have been planted over waterproof materials. It usually covers a large area with focus on improving overall energy efficiency to help with the buildings cooling and heating costs. (1) Green roofs help the environment by cooling the city, cleaning the air, allowing us to manage stormwater, and it even creates habitat. (2)
Next week, Scott Arboretum will be holding their Guided Green Roof Tour on the Arboretum grounds; the PA Horticultural Society will be holding PECO Green Roof Tour; the Green Roof Professional (GRP) Training is coming to Philadelphia; and yesterday, the Green Roofs for Healthy Cities (GRHC) announced that the city of Philadelphia and the PA Horticultural Society will be co-hosting the 9th Annual 2011 Green Roof & Wall Conference with CitiesAlive that will be held in Philadelphia this year.
