Description:

A relatively unusual shrub with airy spikes of lilac-purple flowers throughout the summer, distinctively palmate-leaves; can be treated like a perennial and cut back each spring, as it flowers on new wood and regrows vigorously

Ornamental Features

Chaste Tree has panicles of lightly-scented lilac purple flowers rising above the foliage from early summer to early fall. It has green foliage throughout the season. The fragrant palmate leaves do not develop any appreciable fall color. The fruit is not ornamentally significant.

Landscape Attributes

Chaste Tree is an open multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

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.

Chaste Tree is recommended for the following landscape applications;

  • Hedges/Screening
  • General Garden Use

Planting & Growing

Chaste Tree will grow to be about 15 feet tall at maturity, with a spread of 10 feet. It tends to be a little leggy, with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 50 years or more.

This shrub does best in full sun to partial shade. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This species is not originally from North America.
