Crataegus triflora is an uncommon hawthorn species of the south-eastern United States, of known by the common name three-flowered hawthorn.
It is a multi-stemmed shrub 3 to 5 metres (10 to 16 feet) tall.[1] The flowers are quite large for hawthorn flowers, and occur in small clusters (not necessarily exactly three to a cluster). Although rarely cultivated, it can be very attractive if well grown.[2]
