Green Roof 3-layer sedum mat system

With the 3-part sedum mat system, you can independently design your green roof. You can choose from three different sedum mat types: standard sedum mix mat, wild flower mat and bees and butterfly mat.

  • Sedum mix mat (standard, best-selling): fertilize one to three times a year.
  • Wildflowers mat (wildflowers and ornamental grasses): mow and fertilize once or twice a year.
  • Bees and butterflies matt (ornamental grasses, perennials and herbs): fertilize one to three times a year.

The tool below will advise you on the amount of sedum mat, substrate, drainage and gravel required for your roof. Choose which surface you want to cover with sedum (the green roof surface), taking into account that you leave at least 10cm space between the roof edge and the sedum rolls to be able to lay down gravel for good drainage and a nice end result.

You can also indicate your preferred delivery date below. Please note that delivery generally takes place on Thursdays and Fridays and that at least 3 working days are required behind the scenes to prepare the order.




Sedum is an easy plant, also known as stonecrop because of the greasy leaves. The plant has the property to absorb and store water well – this means it can also thrive in drier periods. The flowers of sedum plants are a magnet for butterflies and bees.

Twelve kinds of sedums are used in the standard sedum mix mat. The wildflower mat has different wildflowers and ornamental grasses and the bee and butterfly mat is a combination of sedum, different types of ornamental grasses, and a mix of forty perennials and herbs. These plants are essential for butterflies and bees.

The sedum mats have a dry weight of 40 to 55 kilograms per square meter (including substrate roll and drainage). When it is saturated with water, it is 65 kilograms. It is possible to install the mats on roofs with an angle of up to 10 degrees.
