Green roofs- sticky catchfly

I’m very please to have recently received planning permission for and installed this green roof on a property in Stirling. I have increased it’s biodiversity value by using a 10cm plating substrate and choosing species of regional botanical relevance in particular sticky catchfly of local provenance, an amber listed (near threatened) species that grows in the wild with in 1km of the property. A beautiful pink flower, often associated with volcanic geology, sticky catchfly is threatened by over grazing and scrub encroachment.P1060368
