When people think of green roofs, many of them tend to think of a roof covered in grass or perhaps wild flowers such as those typically found in a meadow like corn flowers, poppies and marigolds. These do exist, but typically it is sedum roofs in the UK that are most popular amongst green roofing specialists and for some very good reasons. However, when mentioned to clients, the term ‘sedum roof’ often gives rise to the question ‘what is sedum?’ and then with the follow up question of ‘why use sedum?’
Well, it is these questions that we hope to answer here.
What is Sedum?
There are over 600 varieties of sedum plants and are found throughout the northern hemisphere. They are a flowering plant and are commonly known as stonecrops on the grounds that many of the genus still manage to grow and thrive in some quite challenging locations. As succulents they have water storing leaves and their flowers mainly have five petals.
The sedum plants are found in a variety of habitats and so naturally differ in their requirements, some thriving in hotter climates while others prefer a cooler environment. Putting their pretty flowers to one side, it is this diversity alongside their robust nature that makes them so popular amongst gardeners and in more recent times by roofing specialists as an integral part of their green roofing systems. However, it is worth noting that though many sedums flourish in tough environments there are just as many that like a rich fertile soil.
Why do we like to use sedum on our green roofs?
Sedum roofs offer a robust vegetation covering which means limited maintenance work for our clients. Due to the obvious location of roofs, they do tend to take the brunt of the weather at all times of the year. As mentioned earlier, the sedum plants are tough and so are able to weather extreme conditions and yet still look good!
