Comments
The roof is sited 800ft up the Pennine Moors, on an East facing aspect. Given that most years the roof has lying snow for a couple of weeks, and the rest of the time is soaked, establishment of the plug plants has been pretty successful, though slower than in less exposed locations. Full coverage is expected this year, almost 3 years after planting. All plants have been locally sourced in order to be hardy in such a location.
