Green roofs are excellent for the environment. Not only do they provide a layer of insulation that reduces your heating costs, but they also release valuable oxygen back into the air and help remove air pollution. When deciding what type of plant to grow on your green roof, there is one choice that stands out among the rest: sedums. In fact, green roofs are often known as sedum roofs.
If you're aiming to build an eco-friendly, energy-efficient home, be sure to talk to your roofing contractor about sedum roofs and ask if he or she would recommend one for your home. Here's a little more information about sedum roofs to help guide your conversation:
What are Sedums?
Sedums are a type of succulent plants that have thick, fleshy leaves and stems. They use their excess flesh to store water and nutrition, so that they do not become dried out in case of a drought. There are many different varieties of succulent plants, some of which even have fleshy, underground water storage units in their roots.
Benefits of Sedums for Green Roofs
The obvious benefit of choosing succulents for your green roof is that they are less likely than other plants to die when rain is scarce. As long as you have a moderate amount of rainfall, you can likely avoid installing an irrigation system in your green roof if you plant succulents. They are excellent at absorbing rainwater, so when it does rain, you won't have as much runoff to deal with. Succulents are generally very tolerant of air pollution, making them a good choice for green roofs in urban areas.
Kinds of Sedums
There are hundreds of kinds of succulents that are compatible with green roofs. Your local roofing contractor will be able to recommend some that thrive in your particular climate. Common choices include:
Sedum album, a succulent plant that has white blooms that emerge in the summertime. This is a short plant which only reaches about 6 inches in height. In the winter, sedum album turns red in color. It prefers full sunlight.
Sedum sexangular, an even shorter succulent that grows to 4 inches in height and will tolerate some shade. This variety has yellow flowers and also turns red in the winter.
Installing a green roof on your home is an excellent choice for the environment. You'll be playing a role in preserving the earth for generations to come. Make the choice even easier by choosing sedums for your green roof. They require less care than other plant varieties, and they're quite attractive with their summer blooms and deep winter colors.
