species that thrive amongst the crevices, ledges, rocks and
scree slopes of even our highest mountains. Ledges and crevices
High mountain ledges and rock crevices are important places for
some of the rarest mountain plants, particularly where veins of
base-rich rock break the surface. Their inaccessibility to sheep

water flushing through them and the shade of the north-facing
slopes create conditions suitable for species that would
normally be associated with woodland. In summer, these aptly
named tall-herb ledges can provide some of the most attractive
and spectacular displays of wild plants in the mountains. They
often have the appearance of hanging gardens, supporting plants
with names such as wild angelica, ladies mantle, globeflower and
