General tree description
Crataegus x lavallei is thought to be a hybrid of the Cockspur thorn C. crus-galli and the semi-evergreen C. stipulacea / C. mexicana. It may grow up to to 12 metres tall, with a dense, level shape. The habit is perhaps more spreading and lax than the 'Carrierei' clone. Its bark is grey and scaly, and there are few thorns. It has glossy green leaves up to 10cm long, with the lowest third untoothed. The flowers are white, 2.5cm across, on woolly stalks, appearing in early summer. The fruits are 18mm orange-red or dull scarlet haws, lasting through winter. The leaves remain almost evergreen until they drop in early winter.
