A cultivar of the Balkan ash selected in the United States, Moraine ash has an upright, oval-shaped crown and keeps it leaves longer than most other local deciduous ashes. Fall color is a pleasant yellow. As the leaves drop, the clusters of twisted 1¼ inch samaras become more conspicuous and cling on into winter. See Moraine ash lining the north side of Hanover Street south of California Ave in the Stanford Research Park, and placed in paired planters where nearby College Terrace streets dead end onto California Ave.

Botanical nomenclature has been changing, with Fraxinus pallisiae and F. angustifolia both proposed for the species name.
