Genista is a genus of deciduous and evergreen shrubs that are native to Europe and Africa. These shrubs are known for their vibrant yellow flowers and the ability to thrive in poor soils, making them a popular choice in gardens and landscapes. Genista can grow up to 1.5 meters in height and 1.5 meters in width, depending on the variety.

Genista produces flowers in spring and summer, with some varieties flowering into autumn. The flowers are usually yellow, although some species produce white or pink flowers. The foliage is typically small and needle-like, with a bright green color that contrasts beautifully with the flowers.

Genista is best planted in a position with full sun and in well-draining soil. These shrubs are drought-tolerant and can thrive in poor soils, making them suitable for planting in rock gardens, borders, or as a specimen plant. They require minimal maintenance, but regular watering is necessary, especially during dry periods.

Genista benefits from feeding in early spring before new growth appears, using a balanced fertilizer with a high phosphorus content. It is also essential to prune Genista after flowering to maintain a compact and bushy habit.
