Crataegus x lavallei is commonly known as Lavalle Hawthorne. This is a hybrid species of hawthorn that is appreciated for its ornamental qualities, such as its beautiful flowers, attractive foliage, and distinctive fruit. The Lavalle Hawthorne tends to have a more upright growth habit and produces clusters of white flowers in spring, followed by small, red fruit that can be attractive to birds and wildlife.

The other options listed do not correspond to this specific plant. Star Magnolia refers to a different species known for its large, star-shaped flowers in early spring. Copper Beech is a term used for a different tree with distinctive purple foliage. The Tulip Tree, known for its large tulip-shaped flowers, is another separate species altogether. Thus, the correct identification of Crataegus x lavallei as Lavalle Hawthorne is based on its specific characteristics and name recognition in horticulture.
