M-Tray modular green roof system, comprising plastic carrier / drainage module, free draining low nutrient substrate, sedum mix grown from seed and recycled polyester filtration membrane.

A mix of sedum for base cover of the M‐Tray® modules with a variety of low‐growing, perennial wildflower species. These plants are tolerant to dry conditions and suitable for substrate a depth of 100 mm.

The wildflower plants will produce flowers up to a height of approximately 50 cm and attract bees and butterflies. As it is made up of a wide range of native (& wild origin) flowering species and grasses to maximum diversity and reduce the amount of dead vegetation at the end of the summer.

Wildflowers often take 2‐3 years to fully germinate and flower, and some species are viable only as annual and biennial flowers, so new seeds should be broadcast regularly.
