Sunsation Barberry (Berberis thunbergii ‘Sunsation’) is a compact, deciduous shrub known for its vibrant, golden-yellow foliage that intensifies in the sunlight. Its rounded, dense form makes it an attractive choice for borders, foundation plantings, or mass plantings in the landscape. Small, sharp spines line the branches, adding texture and a natural deterrent, while tiny red berries may appear in late summer to fall, attracting birds. The foliage maintains its bright color throughout the growing season, creating a striking contrast with darker greens in mixed plantings.
