Cytisus × boskoopii ‘Boskoop Ruby’ is a striking deciduous shrub known for its masses of deep ruby-red, pea-like flowers that smother its slender, arching stems in late spring to early summer. The vibrant blooms contrast beautifully against the small, mid-green leaves, creating a dazzling display of colour. This low-maintenance, drought-tolerant plant (once established),  thrives in poor, well-drained soils, making it perfect for wildlife-friendly gardens, coastal planting, and sunny borders where it can attract pollinators.
