Fraxinus pennsylvanica Urbanite®
Urbanite Green Ash
Fraxinus americana Urbanite®
Fraxinus biltmoreana Urbanite®
Native to (or naturalized in) Oregon:
- Broadleaf deciduous tree, dense, broadly pyramidal, to about 50 × 40 ft (15 × 12 m). thick bark. Leaves large, thick, usually 9 leaflets, occasionally 11, margin entire, glossy green, light green to silvery below, bronzy in fall. Seedless.
- Hardy to USDA Zone 5 Selected by Willet Wandell from seeds collected in 1965 from a tree in Danville, Illinois (PP 6,215; 1988).
- What species?: "This plant was initially identified as F. pennsylvanica [green/red ash], but Dirr (1997) [should be Dirr (2009), p.451], Jacobson (2003) [Plant of the Month: November 2003. Urbanite® Ash] and others have pointed out the error. Some recent collections of this cultivar have confirmed its hexaploid status (J. Campbell 2016.09-6, 7, 10, 12, 94 & 95 at NY)" ( Campbell, J.J.N. 2017 Phytoneuron 28: 1–36). This suggests that Urbanite® is not a green/red ash but rather is a white ash and should recognized as Fraxinus americana Urbanite® or, as according to Campbell, as Fraxinus biltmoreana Urbanite®. It is likely that the nursery industry will be slow to incorporate such a change.
