Yellow Broom, is a low-growing, mat-forming deciduous shrub that hugs the ground with trailing, spreading stems. In late spring to early summer, it erupts in a cheerful display of bright yellow, pea-like flowers that nearly obscure its fine, hairy foliage. Native to rocky slopes and dry hillsides of southern Europe, this tough little groundcover excels in challenging sites — thriving in poor, gravelly soils where drainage is sharp and competition is low. Its prostrate habit makes it an exceptional choice for rock gardens, slopes, retaining walls, and the front edges of sunny borders, offering season-long interest with minimal maintenance.
