As the top photographs show, River Hawthorn can form dense colonies in its habitat of moist bottom lands. Wild critters enjoy the thick shelter and the abundant fruit.

"Crataegus" is from the Greek "cratus" meaning "strength".  Linnaeus named this genus in 1753 and Thomas Nuttall named this species in 1840 from a specimen he collected in 1834 "along rivulets in the Rocky Mountains".

Various species of Hawthorn trees have attractive shiny serrated leaves, numerous clusters of white flowers, red or blue berries, and they grow to about 20 feet tall in the foothills and mountains of the Southwest. They hybridize easily and species are thus difficult to identify. Hawthorns are not a common tree, but because they produce such an abundance of berries, they are sometimes planted to attract wildlife and thus they are becoming more common.

"Crataegus" is from the Greek "cratus" meaning "strength".  Linnaeus named this genus in 1753.
