Sorbaria False Spirea

If you plant Sorbaria false spirea, don’t expect a prim and proper shrub that knows its place. The charm of false spirea is entirely different. Those who choose to grow Sorbaria shrubs must be ready for the plants’ unruly nature.

These shrubs offer masses of overarching branches, with dark green, pinnate leaves. They also supply billowy sprays of summer flowers.

Native to Eastern Siberia, China, Korea and Japan, false spirea shrubs grow to 10 feet high and wide, and keep spreading. Sorbaria false spirea grow suckers that turn into new plants. Because of this, your false spirea is likely to spread out and take over unassigned space if you let it.

Landscape Attributes

Sem False Spirea is a multi-stemmed deciduous shrub with a more or less rounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This shrub will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics.

Sem False Spirea is recommended for the following landscape applications;

  • Mass Planting
  • Hedges/Screening
  • General Garden Use
  • Container Planting

Planting & Growing

Sem False Spirea will grow to be about 3 feet tall at maturity, with a spread of 4 feet. It tends to fill out right to the ground and therefore doesn’t necessarily require facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub does best in full sun to partial shade. 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 somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America.

Sem False Spirea makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its height, it is often used as a ‘thriller’ in the ‘spiller-thriller-filler’ container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when grown in a container, it may not perform exactly as indicated on the tag – this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception.
