Crataegus × lavallei
kra-TEE-gus x la-VAHL-e-i
Native to (or naturalized in) Oregon:
- Deciduous tree, 20-30 ft (6-9 cm), erect, open branching but dense, asymmetric growth habit. Stout thorns, 5 cm long. Leaves simple, about 5-10 cm long, alternate, serrated, but often entire and undulate from middle to base, lustrous dark green above, pubescent below. Flowers white, 1.5 cm wide. Fruit (ca. 2 cm diam.) brick red to orange-red speckled with brown, contains 2-3 nutlets, persists into winter.
- Sun, as adaptable as any hawthorn
- Hardy to USDA Zone 4 Hybrid between the female partent C. mexicana and the male parent thought to be C. calpodendron. Apparently, there are two clones from this cross, one is vigorous, sets few fruit, and has reddish young twigs. The other is less vigorous, set more and larger fruit, and has greenish twigs. The second clone may be 'Carrierei', which was named in 1883 after the French horticulturist Elie Abel Carriere (1818-1896) (Jacobson, 1996). In the nursery trade, 'Carrierei' is not usually identified, but rather sold as Crataegus × lavallei.
- lavallei: after Pierre Lavallèe (1836-1884), founded the Arboretum Segrez, in France, where the trees originated
- Oregon State Univ. campus: east of north entrance to Withycombe Hall.
