Spiraea japonica ‘Shirobana’, also known as the tricolor spirea, is a remarkable summer variety known for its unique bicolored flowering. This deciduous shrub develops a compact and rounded habit, slightly wider than it is tall, ideal for borders, mass plantings, and foundation plantings. In summer, its corymbs simultaneously display white, pink, and dark pink flowers on the same plant, creating a dynamic and original decorative effect. Its finely toothed medium green foliage offers good density and highlights the abundant blooms. Easy to care for and very hardy, Spiraea japonica ‘Shirobana’ prefers well-drained soil and a sunny exposure to maximize flowering. It is an excellent choice for bringing color, contrast, and lightness to Nordic landscape designs.
