Early spirea

Flowers of early spirea.

Early spirea or Thunberg spirea is one of the first spireas to flower in early spring. The 3- to 5-feet-high shrub starts out with lovely white umbel-shaped flowers, followed by fine-textured, light green foliage that eventually changes to a bronzy-orange fall color. Great plant for accent or used in a shrub border.
