Dyer’s Greenweed | Genista tinctoria
The deciduous dyer’s greenweed is native to Central Europe and western Asia. This small slow-growing prostrate to erect shrub is a member of the Fabaceae family and rarely grows higher than 80 cm (32 in). It has glossy green leaves and bright yellowthat appear in early summer, followed by the typical brown pods.
The dwarf form ‘Plena’ has double flowers. G. tinctoria grows best in a sunny position and does not mind hot, dry conditions. It is therefore ideal for exposed places such as roof. The must be well-drained and not too rich. The plant can be cut back by one-third after flowering in order to keep it in the right shape. At the same time softwood or greenwood cuttings can be taken, which will root very easily. The container must be well protected during winter. Note that all the parts of the plant are poisonous.
