What plants are the green roofs made of?
The green roofs that Marvy Green sells consist largely of sedum. Sedum is a type of succulent plant that is very suitable for greening your roof due to its natural properties.
Sedum is also popularly referred to as stonecrop and is a genus of the succulent family; Crassulaceae. Succulents “succulents” are plants known for being good at storing water. In the case of sedum, the water is stored in the leaf. This ensures that during a dry and hot day the loss of moisture is minimized. Sedum needs little water and nutrients to survive. This makes the plants extremely suitable for green roofs. In addition, Sedum, due to its roots in dry and/or cold areas, is used to more extreme weather conditions.
Advantages of a sedum green roof
- A sedum roof is self-sustaining and maintenance is minimal
- It is a cost-effective greening method
- Sedum can take root very shallowly
- Roofing with sedum is lightweight due to the low substrate layer depth
- The vegetation can withstand drought well
When installing a green roof?
Sedum roofs can in principle be installed all year round. Delivery and installation of the green roof are only possible under frost conditions. When it freezes it is not possible to roll up the vegetation blankets. Spring and autumn are best suited for green roofs; you run the least risk of the plants drying out and these are favourable seasons for the growth of the sedum. Did it just rain? Then be careful and take slippery conditions on the roof into account.
A green roof with sedum vegetation is hardy and perennial plants are used in the mats you buy from Marvy Green. Sedums go into dormancy in winter and will then turn red. In the case of mixed mats, you will see that grasses, herbs, and host plants retreat slightly in the winter, and then bloom again in the spring!
