Genista tinctoria is a deciduous shrub growing to 2ft x 3ft. A member of the pea family. Flowers appear from June to September and the seeds ripen from August to October. It is an important foodplant for a range of scarce moths.
Easily grown in a light well-drained soil in a sunny position. Prefers acid soil. A cold tolerating plant.
Does not transplant well and should only be transplanted when young.
A strong yellow dye is obtained from the whole plant – especially from the flowers. When overdyed with woad it produces a lovely green.
The seedpods turn black in late summer and when ripe burst open making a distinct “popping” sound. Each pod contains about 5 seeds.
The seeds require a period of cold stratification and are best sown in the autumn in a cold frame or pre-soak stored seeds for 24 hours in warm water and sow in February and place in a cold frame. Seed placed in a cold frame will benefit from the natural winter cold conditions which should offer ideal conditions for germination to occur in spring when the weather warms up. Transplant seedlings when large enough to handle to 8cm pots. Acclimatise and plant out when well grown and after all danger of frost has passed – about June.
Prefers sunny dry locations.
