Dyers greenweed is found in rough grassland, meadows and heaths and is a native deciduous shrub. A slightly acidic soil is preferred. Deep yellow flowers are carried on tall stems and they can look quite striking.
The bright yellow flowers are great for attracting pollinators. It is also a food plant for around 20 moth species, several of which are quite rare, having declined in recent years due to agricultural grassland improvement. It is also important to the life cycle of other insects such as leaf beetles and sawflies.
The flowers of Dyers greenweed have traditionally been used as a natural yellow dye.
