Report an issue with this species
Crataegus ambigua, or Russian Hawthorn, is a resilient small ornamental tree, valued for its deeply-lobed, dark green leaves, abundant white spring blooms, and attractive red pome fruits. Its fall brings golden foliage, and its gnarled branching offers winter interest. This tree's tolerance to various environmental conditions makes it suitable for urban settings, though its stems are armed with purple thorns.
