Green roof plants are not one-size-fits-all.
The individual requirements of each green roof design must be taken into consideration. Your LiveRoof® Licensed Grower is an experienced horticultural professional who will examine the particular needs of project and assist in selection of the best plants to bring your design to life.
Anyone who travels to different climate zones observes that typical landscape plants vary based on what is well-suited to the unique challenges of that environment. On the roof, attention to local conditions is even more critical. For example, in Toronto, plants that can handle the rapid changes in temperature and long winters are a necessity. In much of Texas, a plant palette that can handle summer’s prolonged heat, high nighttime temperatures, low precipitation rates and heavy humidity must be developed. Some green roof companies also tout having a horticulturist on staff, but we have dozens, in different climates, most with decades experience growing plants for and in that local environment.
While some plant species produce relatively stable seed and resultant offspring, many green roof plants prevalently used today produce offspring that is variable in appearance, vigor, hardiness, and overall performance. Some seedlings may be genetically lucky, with excellent color and growth, and others may be genetically weak and fail to hold up in challenging rooftop conditions.
