Fls shallowly funnelform. Sepals 6.5-8 mm long including awn, oblong or oblong-lanceolate, the inner with pink hyaline margins, with hairs as on pedicels; apex mucronate. Petals 12-18 × 9-11 mm, broad-obovate, pink with crimson veins; claw 1/4-⅓ limb, crimson; apex rounded. Filaments crimson; anthers dark purplish.

G. maderense has been widely cultivated in N.Z. in recent years. Seedlings are sometimes so numerous that they are a nuisance. In N.Z. this plant is sometimes known as G. anemonifolium, a synonym of G. palmatum Cav., a related Madeiran endemic.
