The Patmore Ash is a seedless male cultivar of Fraxinus pennsylvanica, which is native to eastern and central North America. It is a medium sized deciduous tree that is fantastically versatile for use in urban landscapes with its fast growth rate. It is tolerant of moist or dry soil and a range of soil types, as well as pH conditions. 

Fraxinus pennsylvanica ‘Patmore’ is drought tolerant and can be of great use in dry landscapes. It also tolerates urban pollution very well and can be used as a street tree, park tree, or planted in larger urban landscapes. This tree has a beautiful, uniform upright growth pattern with a strong leader and a symmetrical, rounded crown. It is therefore considered to be one of the best selections for use as a shade tree. The Patmore Ash grows to a height of 50-70 feet with a spread of 35-45 feet.

The Patmore Ash should be planted in full sun for best results. It blooms in the springtime – the flowers are greenish purple and inconspicuous. The leaves are deep green in color, and the leaflets are more deeply serrated than other cultivars.

Fraxinus pennsylvanica ‘Patmore’ can be damaged by severe winter and ice storms. Surface roots can be a problem for street trees. It is hardy and can tolerate a range of conditions.
