Lime Mound Spiraea is a compact, mounded shrub prized for its ever-changing foliage and seasonal color. In spring, new leaves emerge a brilliant chartreuse-yellow, lighting up the landscape. As summer progresses, the foliage deepens into a bright lime green, serving as a perfect backdrop for the clusters of rosy-pink flower heads that bloom from late spring into early summer. In fall, the foliage shifts to striking shades of orange, red, and purple, extending its multi-season interest.
