This small herbaceous, branched perennial is a garden rockery or wall plant. It has become established on shady old walls in towns and gardens, fairly near to its garden parents but vigorous colonies are now established in the wild. The golden yellow flowers, with two outer lips, grow in one-sided spikes and flower between May and October. The delicate leaves are pinnately divided, each having three rounded lobes and are green above and blue-green beneath. It is a native of the central and eastern Alps and since the early 19th century has become thoroughly naturalised in Britain in urban areas, first being recorded wild in Britain in 1796.
