Plant Varieties

Sedums are the "go-to" choice for extensive green roof vegetation.

Living conditions can be very demanding on rooftops. Plants are subject to extreme temperatures, wind and extended droughts. It is crucial to choose particularly hardy species for extensive green roofs. Sedum, chive, carnations and thyme are succulent plants highly resistant to the multiple sources of stress associated with rooftop living conditions. These plants are able to establish themselves and create long-lasting plant cover. They are capable of withstanding extended dry periods and then resuming their growth.

These plant varieties, which vary in height, are blended to obtain plant cover that remains attractive and uniform over time.
 

Standard Plant Mix- Plant cover with a vibrant appearance.

Plant cover based on the standard plant mix is low-lying and uniform, but wild. It features colors that change with the seasons and the intensity of the stresses to which the plants are subject. The overall appearance can vary from green, during periods of active growth (spring and fall) to bronze or even reddish-brown when plants are exposed to water shortages or frost.

The flowering season is generally May/June, during the summer or in September, depending on the species planted. Flowers tend to be white, yellow or pink. The location and exposure of the project, as well as the degree of maintenance also
have a significant impact on the condition of the plants and therefore the general appearance of the roof. These variations in appearance can be enhanced by maintenance.

Maintenance

Plant cover using the Standard Plant Mix requires minimal maintenance: the main upkeep operations (described in the ''Maintenance'' section) can be carried out with only 2 to 4 maintenance sessions per year. To provide an active growth and blooming, we recommend visiting the roof more often.
