Description:

A delicate garden shrub bathed in pure white flowers along thin, wispy branches, very beautiful when in flower; attractive light yellow-green foliage all season long, very fine textured and refined, somewhat loose appearance, needs regular pruning

Ornamental Features

Thunberg Spirea is covered in stunning clusters of white flowers along the branches in early spring before the leaves. It has lime green foliage which emerges chartreuse in spring. The tiny grassy leaves turn an outstanding orange in the fall. The fruit is not ornamentally significant.

Landscape Attributes

Thunberg Spirea is a multi-stemmed deciduous shrub with a shapely form and gracefully arching branches. It lends an extremely fine and delicate texture to the landscape composition which can make it a great accent feature on this basis alone.

This is a high maintenance shrub that will require regular care and upkeep, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Thunberg Spirea is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use

Planting & Growing

Thunberg Spirea will grow to be about 5 feet tall at maturity, with a spread of 5 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub should only be grown in full sunlight. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America.
