Dotted Hawthorn has a good sized native range from southwest Quebec & southern Maine down to northern Georgia to southeast Missouri up eastern Iowa into southeast Minnesota to all around Lake Michigan into southeast Ontario in lowland wet mesic to upland dry sites. It grows about 1 foot/year and lives 50 to 100 years. Narrow oval leaves not lobed with sharp teeth above middle of leaf; turn orange to red in autumn. White flat-topped clusters about 2 to 3 inches wide in late May into early June. It bears one of the larger hawthorn fruit about 3/4 inches in diameter in drooping clusters of dull orange to red with conspicuous white dots, in mid-August into October. it bears thorns about 2 inches long, sometimes compound ones. Cedar Rust can be hard on this species. I've never recognized one in the wild; I've only seen one specimen at the arboretum. It is not grown by conventional nurseries for landscapes. Some native plant nurseries may have some.
