Quercus × bimundorum Crimson Spire™
Crimson Spire Oak
Native to (or naturalized in) Oregon:
- Deciduous tree, narrow columnar, upright, to 45 ft tall and 15 ft wide (~14 × 4.5 m). Leaves alternate, simple, obovate with three to five pairs of rounded lobes, 9-15 cm long by 5-9 cm wide, leaf base is rounded to broadly acute, dark green, rusty red in fall.
- Hardy to USDA Zone 5 Discovered by Willet Wandell in his nursery in Oquawka, Illinois, from a Q. robur seed parent, Q. alba is suspected as being the pollen parent. Introduced in 1994 by the J. Frank Schmidt Nursery, Boring, Oregon, PP 9103.
- bimundorum: Latin, bi, two, and mundus, worlds, hence Two Worlds because it is a hyrid of Q. robur English Oak (from the "old world") and Q. alba White Oak, native to Eastern North America (i.e., the "new world"). Similar in tree shape to that of Q. robur 'Fastigiata' as well as in leaf profile.
- Oregon State Univ. campus: three trees on the south side of Pharmacy.
