Sedum Acre, Crassulaceae

Known in the UK as Biting Stonecrop due to the mildly irritating fluid contained in its leaves. I found it growing at an elevation of about 180m, on the north stone wall of a ruined farm near the Finglen Burn, one of the many large streams on the southern side of the Campsie Fells, a volcanic range of hills in central Scotland.

Semi-visible in the photos, the space between the walls was almost entirely colonised by Urtica dioica, as this plant thrives in the nitrogen-rich soil of long-abandoned human sites.

This was the first plant ID I posted on my blog, it all started with a tiny succulent! I also have a small bit of the very plant in the bottom photo growing in a pot on my windowsill.
