Curly leaf spirea is a flowering deciduous shrub that originates from Japan and China. This hardy, easy to grow plant has a rounded, compact habit and bears soft clusters of pale pink flowers in mid to late summer. Spent flowers can be removed to extend flowering. Its unique foliage is dark green, curly and crinkled in appearance. Best grown in full sun and tolerant of a wide range of soils, curly leaf spirea is a highly versatile landscape shrub that looks great in mixed borders, low hedges or planted in masses.
