Gold Mound Spirea (Spiraea japonica ‘Gold Mound’) is a compact, deciduous ornamental shrub prized for its bright golden-yellow spring foliage that gradually softens to chartreuse as summer progresses. In mid-summer it produces clusters of soft pink flowers that contrast beautifully against the foliage, attracting pollinators like bees and butterflies. Its dense, mounded habit and fine-textured leaves make it an excellent low hedge, edging plant, or accent in mixed borders. In Regina’s climate, it is hardy and dependable, with foliage colour being most vivid in full sun.
