Crataegus uniflora, commonly known as the dwarf hawthorn or one-flower hawthorn, is a small deciduous shrub or occasionally a small tree native to the southeastern United States. It typically grows about 6–15 feet tall with a spread of 6–12 feet, forming a rounded to somewhat irregular crown. The trunk or main stems are usually 3–8 inches in diameter, and the branches are armed with slender, sharp thorns that commonly measure 1–2 inches long. Its simple, glossy green leaves are generally 1–2½ inches long and ¾–2 inches wide, often with shallow lobes and finely serrated edges, turning yellowish to bronze in autumn. In spring, the plant produces delicate white flowers that are usually solitary—hence the species name—each flower about ¾–1 inch across, with five petals and numerous stamens. These blooms later develop into small round fruits (pomes) that are typically ¼–½ inch in diameter, ripening to red and persisting into fall, providing food for birds and wildlife. The plant’s twigs are slender and gray to reddish-brown, while the bark on older stems becomes rough and scaly with age. Adapted to sandy soils, dry upland woods, and open pinelands, this compact hawthorn is valued in native landscapes for its modest size, wildlife value, and tolerance of relatively dry conditions.
