What are Green Roofs?
A roof is an unlikely place for a beautiful landscape. However, many shrubs, grasses, asters, bulbs, agaves, poppies, tick seeds, and many other plants can thrive on our roof.
Green roofs are multifactorial in their performance and function. They help improve energy efficiency from an additional layer of insulation provided by the growing media. They also reduce stormwater runoff by trapping and stopping precipitation, reducing pressures on local stormwater systems. Green roofs combat the urban heat island effect by lowering temperatures and improving local air quality. They also provide greater biodiversity and increase green spaces in areas that normally lack them. Green roofs are an example of how building infrastructure can blend in with the natural environment rather than collide with it.
Shrubs for green roofs
• Coccoloba uvifera
• Caesalpina pulcherrima
• Calliandra haematocephala
• Carissa grandiflora
• Cassia didimobotrya
• Senna reticulata, among others
We share this INTA catalog where the main species studied at the Floriculture Institute are presented to be used in green roofs, and their most relevant characteristics are mentioned: https://inta.gob.ar/sites/default/files/script -tmp-inta _-_ catalog_of_plants_for_green_ roofs.pdf
What are living walls?
Like a green roof, a living wall is an artificial growing environment created to smooth or "green" otherwise rigid surfaces, often in urban areas with no other vegetation. However, while green roofs are on top of buildings, living walls are installed on vertical structures such as walls, fences, and columns.
While some living walls are simply support systems that grow on the vine, the more complex examples consist of modular containers or geotextiles that contain both soil and plants. Since this challenging environment offers little room for root growth and requires frequent watering, great care must be taken during plant selection. Evergreens, vines, and sprawling plants are generally good options for making the surface and support structure invisible behind a lush curtain of greenery.
