Ashy Spirea 'Grefsheim'
FamilyRosaceae
Spiraea × cinerea 'Grefsheim' is a graceful spring spiraea, forming a fountain of arching branches covered with small white flowers in April-May. It is distinguished by its very early and dense flowering, in tight clusters along the branches, creating a spectacular snowy effect. Its narrow, gray-green, deciduous foliage complements the lightness of its silhouette. 'Grefsheim' develops a flexible, slightly spreading habit, more contained than Spiraea × vanhouttei, while maintaining a strong presence in the garden. Ideal for low hedges, as a standalone plant, or in a free-form bed, it is very hardy, tolerant of severe pruning, and low-maintenance. It is a reliable choice for a maintenance-free flowering spring.
