Nippon Spirea 'Halvard Silver'
FamilyRosaceae
Spiraea nipponica ‘Halvard Silver’, commonly known as Japanese Spiraea ‘Halvard Silver’, is a deciduous shrub with a rounded, compact habit, prized for its abundant flowering and finely textured foliage. In late spring, it is covered with a multitude of small, pure white flowers grouped in dense corymbs that line its arching branches, creating a spectacular effect. Its bluish-green to dark green foliage forms a dense, regular mass, ideal for structuring beds, low hedges, or borders. Hardy and easy to maintain, Spiraea nipponica ‘Halvard Silver’ tolerates pruning well after flowering to maintain a compact silhouette. It prefers well-drained soil and a sunny exposure to ensure maximum flowering and healthy foliage.
