|discussion=<p>In the flora area, <i>Crataegus laevigata</i> is known only from the San Juan Islands; alleged wild records from elsewhere in North America proved to be misidentifications. The species is widespread in central Europe and scarce beyond that. Woodland hawthorn is more shade-tolerant than many other species, hence the common name.</p><!--
--><p><i>Crataegus laevigata</i> has more shallowly incised leaves and more obtuse lobes than other species in ser. <i>Crataegus</i>.</p><!--
--><p>Pink- or red-petaled cultivated forms attributed to <i>Crataegus laevigata</i> are important ornamentals; they are usually cultivars of C. ×media Bechstein. Similar colored cultivars of true <i>C. laevigata</i> are scarce in North America.</p>
