The Spiraea japonica, or Japanese Spirea, is a hardy, mounding deciduous shrub loved for its vibrant foliage and clusters of delicate pink flowers that bloom in early summer. Its leaves often emerge in shades of gold or bronze before turning a lush green, and many varieties offer striking red or orange color in the fall. Because it is incredibly tough and adapts to most soil types, it is a "workhorse" in the landscape, perfect for mass plantings, borders, or adding a reliable splash of color to a garden bed.
