About
Crataegus arnoldiana is a deciduous tree characterized by its dense, zigzagging branches and thorny structure. The leaves are dark green, shallowly lobed, and have a serrated edge. In late spring, it produces clusters of white flowers that feature pale yellow anthers. These flowers give way to sizeable red berries, which can reach up to 1.5 cm in diameter.
