Landscape Attributes

Winterthur Winterhazel is a dense multi-stemmed deciduous shrub with a shapely form and gracefully arching branches. 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 is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season's flowers. It has no significant negative characteristics.

Winterthur Winterhazel is recommended for the following landscape applications;

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

Planting & Growing

Winterthur Winterhazel will grow to be about 6 feet tall at maturity, with a spread of 10 feet. It has a low canopy with a typical clearance of 1 foot from the ground, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 40 years or more.

This shrub performs well in both full sun and full shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
