Low-growing deciduous barberry with a horizontal habit, Berberis thunbergii 'Golden Horizon' produces pale cream flowers in spring and bright red berries in autumn. Its bright yellow-green oval leaves turn orange in autumn, providing striking seasonal colour. The compact habit (about 1 m x 1 m) makes it suitable for ground cover, borders, raised beds and containers, and it supports pollinators while remaining hardy in garden conditions.
