A plant with slightly funnel-shaped flowers (18 to 25 mm) which have five pink petals, usually covered with a tracery of purple lines. These lead towards the lighter-coloured centre of the flower where the anthers are tipped purple. Each petal has a shallow cleft at its outer edge. The leaves are five-lobed, palmate and deeply veined. A slightly hairy plant, it is quite erect, occasionally reaching to 60 cm

The parent species are G endressi and G versicolor; the hybrid forms a spectrum of variation between the two species, and there are many garden forms which will persist in the wild.  G endressii has veins paler than or same colour as the ground colour of the petals; G versicolor has darker veins.  See Stace (4th edn.) for further details

Petal ground colour pale to deep pink; with or without darker veins.
