Plant Family Guides: Crataegus---Hawthorns Guides
Crataegus monogyna (Single-Seed Hawthorn) is listed in the Invasive Plant Atlas of the United States. The federal government has estimated that nearly 25 percent of the 20,000 plant species native to North America are at risk of extinction, many of these through habitat loss. You can help reverse this trend by planting great native plants in your garden.
