Landscape Attributes

Thornless Hawthorn is a deciduous tree with a stunning habit of growth which features almost oriental horizontally-tiered branches. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This tree 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.

Thornless Hawthorn is recommended for the following landscape applications;

  • Accent
  • Hedges/Screening

Planting & Growing

Thornless Hawthorn will grow to be about 25 feet tall at maturity, with a spread of 25 feet. It has a low canopy with a typical clearance of 3 feet 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 50 years or more.

This tree should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. 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 is a selection of a native North American species.
