FRAXINUS pennsylvanica ‘Patmore’

Ash –

0405 Fraxinus pennsylvanica, commonly called green ash, has the largest growing range of any of the native ashes, extending from Nova Scotia to Alberta south to Florida and Texas. This is a lowland species that is commonly found throughout the State of Missouri in low woods, floodplains and along streams, ponds and sloughs (Steyermark). It is a medium sized tree, typically growing 50-70’ tall. Green ash is primarily dioecious (separate male and female trees). ‘Patmore’ is a male cultivar (ergo seedless) that was originally discovered in 1967 as a seedling mutation of unknown parentage growing in a cultivated area along a street in Vegreville, Alberta, Canada. It was subsequently introduced into commerce in 1976. U. S. Plant Patent PP04,684 was issued on April 7, 1981. ‘Patmore’ is a vigorous, pyramidal tree with a strong central leader, ascending branches and a symmetrical, rounded crown. Clusters of inconspicuous, apetulous, greenish-purple, male flowers appear in April-May after the foliage emerges. Compound, odd-pinnate, glossy, medium green leaves (to 12″ long), each with 7 (5-9) serrate, oval to oblong-lanceolate leaflets (3-4″ long), are attractive throughout the growing season. Foliage turns yellow in fall, with the quality of the fall color often varying considerably from year to year. Ash-gray to gray-brown bark develops distinctive diamond-shaped ridging on mature trees. ‘Patmore’ is very similar in appearance to F. pennsylvanica ‘Marshall’ (also known as ‘Marshall’s Seedless’).
