Plant Profile: Crataegus x lavalleei

Lavalle Hawthorn is a small tree belonging to the rose family, resulting from a hybridization of two hawthorn species discovered at the Arboretum Segrez in France. This tree typically reaches heights of 15 to 30 feet and features a dense, rounded, or irregular shape. It can also develop as a multi-stemmed shrub. In spring, it produces clusters of white flowers that emit an unpleasant fragrance, which are succeeded by red-orange berries in the fall that can last into winter. The foliage showcases attractive bronzy-red hues in autumn, while the branches are armed with thorns that can grow up to 2 inches long.

For optimal growth, plant this tree in average, well-drained soil, ideally in full sun to partial shade. It is adaptable to various soil types, though it does not thrive in overly wet conditions, and once established, it demonstrates drought resistance. Lavalle Hawthorn can serve as a small flowering shade tree or be utilized as a hedge or barrier; however, its thorns make it unsuitable for walkways or areas frequented by children.

Like many hawthorns, Lavalle Hawthorn can be susceptible to pests and diseases, although it is noted for its strong resistance to rust and fire blight. Other potential issues include fungal leaf spots, powdery mildew, cankers, apple scab, leaf blight, and twig blight. In terms of insect threats, it may attract aphids, borers, caterpillars, lacebugs, leafminers, spider mites, and scale insects.
