Our product
THE ADDED VALUE OF FLOWERGREEN ROOFS
We rely on nature more than we realize. Yet urbanization keeps pushing it away. Flowergreen roofs help restore the balance. A biodiverse green roof brings back plants, insects, and birds, improves air quality and cools the city. By reconnecting green spaces, we can revive urban biodiversity and make our cities thrive again. The need is urgent, but the solution is simple.
For flat and sloped roofs
Flower green roofs are suitable for both flat and gently sloping roofs, offering flexible design and easy installation.
Biodiversity with Power
By combining solar panels with a Flower green roof, energy and ecology work hand in hand.
OUR ROOFS THAT BUZZ WITH LIFE
The type of green roof suitable for your project depends on its purpose and the roof’s load-bearing capacity. Biodiverse green roofs feature a thicker substrate layer that allows insects to pupate and thrive.
There are two types of Flowergreen roofs available: the Flowergreen Herba, featuring a vibrant mix of Sedum and herbs that add color, fragrance, and year-round ecological value, and the Flowergreen Flora, which combines over twenty plant species that are highly attractive to bees, butterflies, and other pollinators.
Biodiversity loss is not a problem of the future — it’s already happening, and the time to act is now.
DISCOVER THE IDEAL BIODIVERSE ROOF FOR YOUR PROJECT
Every project deserves a flowergreen roof that fits perfectly. Whether for pitched green roof, solargreen or bluegreen roof, we’ll guide you to the right choice. Answer a few quick questions and receive customized advice from our experts.
FLOWERGREEN HERBA
The lightweight Flowergreen Herba brings your roof to life with color and energy. Its smart structure starts with a drainage layer, followed by at least 70 mm of extensive green roof substrate, topped with the Sempergreen Biodiversity Blanket Sedum-Herbs. Grown with more than 12 Sedum varieties and 30 herb species, it offers a vibrant display of biodiversity throughout the year.
With a minimal saturated weight of 100 kg/m², this system is ideal for roofs with limited load-bearing capacity and can even be applied on slopes up to 20 degrees, turning every surface into a living landscape.

FLOWERGREEN FLORA
The Flowergreen Flora transforms every roof into a flourishing ecosystem. A drainage layer establishes the base, crowned with at least 120 mm of rich, intensive substrate and our vibrant Sempergreen Biodiversity blanket Bees & Butterflies. This distinctive mat is cultivated with over 20 native plant species that attract bees, butterflies, and other pollinators.
Developed in close collaboration with the Dutch Butterfly Foundation and Bee Foundation, it reflects our shared mission to restore nature in the city. With a minimal saturated weight of 210 kg/m², this sturdy system creates stepping stones across urban areas, aiding birds and insects in moving freely between parks, gardens, and natural areas.

QUESTIONS ABOUT BIODIVERSE ROOFS
Get clear answers to your questions about biodiversity on flowergreen roofs, from plant choices and maintenance to combining them with solar panels.
Does my green roof support local biodiversity?
Absolutely. All green roofs provide habitat and food sources for insects. The type of species depends on the vegetation: from Sedum roofs to diverse roofs with herbs and nectar-rich plants. Compared to a gray roof, every system offers a clear ecological gain. Both flat and pitched roofs can be equipped with biodiversity-enhancing systems, including lightweight options.
Which plants are best for biodiversity on a green roof?
Besides Sedum, herbs, native flowers, and host plants significantly enhance ecological value. A diverse mixture attracts more pollinators and supports various life stages of insects.
How do you maintain a biodiverse green roof?
A biodiverse roof typically requires 3–4 maintenance visits per year. This includes fertilizing, removing weeds, and checking drainage. Regular care keeps the vegetation diverse and healthy.
Can a biodiversity roof be combined with solar panels?
Yes, perfectly. Green roofs cool the panels naturally, increasing efficiency and energy yield. Biodiverse vegetation attracts insects without reducing solar performance.
What is the difference between a Sedum roof and a Biodiverse roof?
A Sedum roof is lightweight and ideal for buildings with limited load capacity, providing nectar and greenery. A Biodiverse roof adds herbs, flowers, and host plants, creating much higher ecological value and supporting more species.
