Mauve (H2) flowers, VII–VIII; superb gold foliage in summer, turning lime-green flecked with red in winter; height 10–15cm; spread 21–25cm.
Wild-collected; found on Beinn Nuis, Isle of Arran, Scotland, by Roger Bell; introduced by D. Hutton (Aberfoyle, near Callander, Perthshire, Scotland) by 1971.
Named after the island in the Firth of Clyde where it was found; gold alludes to the summer foliage.
