Genista tinctoria (dyer’s greenweed or dyer's broom) is a species of flowering plant of the family Fabaceae, native to meadows and pastures in Europe and Turkey. Its other common names include dyer's whin, waxen woad and waxen wood.
It is a variable deciduous shrub growing to 60–90 centimetres (24–35 in) tall by 100 cm (39 in) wide, the stems woody, slightly hairy, and branched. The alternate, nearly sessile leaves are glabrous and lanceolate. Golden yellow pea-like flowers are borne in erect narrow racemes from spring to early summer. The fruit is a long, shiny pod shaped like a green bean pod.
