One of the best general purpose shade trees for cold climates; extremely hardy, very clean and tidy with a symmetrical rounded shape and glossy foliage, seedless, adaptable to almost any conditions; popular and justifiably so

Ornamental Features

Patmore Green Ash has dark green foliage throughout the season. The glossy compound leaves turn yellow in fall. Neither the flowers nor the fruit are ornamentally significant. However, the fruit can be messy in the landscape and may require occasional clean-up.

Landscape Attributes

Patmore Green Ash is a deciduous tree 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 tree will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Insects

Patmore Green Ash is recommended for the following landscape applications;

  • Shade
  • Windbreaks and Shelterbelts

Planting & Growing

Patmore Green Ash will grow to be about 49 feet tall at maturity, with a spread of 20 feet. It has a high canopy with a typical clearance of 6 feet from the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a fast rate, and under ideal conditions can be expected to live for 70 years or more.

This tree should only be grown in full sunlight. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. 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. This is a selection of a native North American species.
