Growers at heart. Green by Mission.
Since 1996, we’ve been Replanting the planet. Turning grey into green with roofs, walls and ground covers. Inch by inch, meter by meter, mile for mile.
We bring nature back into the world
Since 1996, we’ve been growers at heart with a clear mission: to restore the balance between people and plants by making cities greener, healthier and more liveable for everyone and every living creature. What began with our roots in horticulture has grown into a global movement, supplying sustainable green roofs, living walls and ground cover systems. Driven by the belief that nature should not be pushed aside in urban environments but woven into them, we transform grey buildings into vibrant green oases – inch by inch, meter by meter, mile for mile.
Why we do
what we do
Plants are more than just biology.
They cool, filter, absorb and protect.
They give energy, beauty and life.
Yet cities are still dominated by grey. Concrete, asphalt, steel.
At Sempergreen, we believe cities can, and must, become greener. Together with our clients, we bring back the positive power of plants to every wall, roof and street.
With nurseries on five continents and partners all over the world, we bring green solutions to every corner of the planet. Our scale means we can deliver directly from stock – whether it’s a small local project or a large metropolitan development. This global reach, combined with local knowledge, ensures that every project gets exactly what it needs to thrive.
From water-retention roofs and solar green roofs to biodiversity blankets and modular living walls – our systems are designed to solve the urgent challenges of today. They help cities adapt to climate change, combat heat stress, reduce flooding, and create healthier places to live. Innovation and sustainability are at the core of every product we develop, always with future generations in mind.
Every square meter of greenery makes a difference. Our systems cool overheated cities, absorb and buffer stormwater, purify the air, and give new habitats to insects and birds. The impact is not only measurable in numbers but also visible in the way people experience their environment: more nature, more beauty, more balance.
Sempergreen and knowledge platforms
Cities as green ecosystems
Urbanisation is not the enemy. It’s our canvas. Every roof, every wall, every surface is a chance to bring nature back into the city. With years of knowledge and experience, we turn any building into a thriving ecosystem. Straight, sloped or vertical – we see possibilities where others see limits.
Mapping a greener future
To show the real impact of our work, we created the Greenmapper. This visual grid highlights how every roof, wall and surface we green adds up to measurable change. It’s our way of making the effect of plants visible – from cooling cities and storing water to boosting biodiversity. Step by step, square by square, the Greenmapper helps us track how we are replanting the planet together.
A global network,
a local touch
With nurseries and partners on five continents, Sempergreen is always close by. We understand the challenges of local climates, regulations and urban environments. Whether it’s a rooftop in New York, a living wall in Hamburg or a biodiversity roof in Sydney – our teams know how to make green thrive everywhere.
