Shirobana Spirea

Shirobana Spirea (Spiraea japonica 'Shirobana')

Shirobana Spirea (Spiraea japonica 'Shirobana'), also known as Shibori Spirea or Tricolor Spirea, is a unique deciduous shrub celebrated for its ability to produce pink, white, and red blooms all on the same plant. This multicolored flowering display, combined with a tidy habit and seasonal foliage color, makes it a charming and eye-catching focal point for borders, foundation plantings, and mixed beds.

Distinctive Features

Shirobana grows 2 to 3 feet tall and wide, forming a compact, rounded shrub. Its narrow, bright green leaves emerge in spring and provide a fresh backdrop for the tricolor flowers that bloom from early to midsummer. Each bloom cluster can include pink, white, and reddish-pink flowers, creating a patchwork effect that looks like three plants in one. Foliage often develops orange or red tones in fall, adding late-season interest.
