Plant Varieties
Green roofs can be designed with a range of soil depths, which will determine which plants are most appropriate. It’s advised that you choose plants that are hardy enough to grow without constant watering, fertilizing or trimming. At the same time, plants that grow quickly and establish tough roots are your best bet for a lush, verdant roof.
Some common green roof plants include:
- Low-growing succulents
- Wildflowers
- Hardy grasses
- Shrubs
- Small trees
- Aromatic herbs
Be sure to incorporate plant diversity and add multiple species to your green roof to give your plants support and improve their chances of surviving.
Choosing Plants for Functionality
The plants you select for your green roof will ultimately determine what you get out of it. If you’re interested in promoting greater biodiversity, for example, you may choose plant species that are attractive to native birds and insects. If appearance is a major consideration, colorful flowers and appealing succulents are a great choice. Looking for minimal maintenance? Free-growing shrubs and bushes offer a great solution.
The best way to choose the appropriate plants is to consult with a green roofing expert offering extensive experience with commercial properties. Your roofing contractor can answer all your questions and guide you toward the plant varieties that are best suited to your goals, as well as which are most appropriate for the unique climate of the Pacific Northwest.
