Shrubs or trees, 40–80 dm. Stems: older trunks usually bearing compound thorns; twigs: new growth reddish green, glabrous, 1-year old dark, shiny red-brown, 2–3-years old becoming dark gray, older ± paler gray; thorns on twigs numerous, usually recurved, shiny, 1-year old dark blackish brown, stout, 3–6(–8) cm. Leaves: petiole 1–2 cm, narrowly winged distally, glabrous, eglandular; blade rhombic-elliptic to broadly rhombic-ovate or elliptic, 4–7 cm widest near middle, subcoriaceous mature (then often blue-green), base cuneate (constricted), lobes 3–5 per side, obscure to well-marked, sinuses shallow, lobe apex usually subacute to obtuse, margins serrate except proximally, veins 6–8 per side, impressed, apex acute to subacute, rarely obtuse, abaxial surface glabrous, adaxial scabrate-pubescent young. Inflorescences 15–30-flowered; branches pubescent or glabrous; bracteoles linear, 1.7 cm, margins glandular. Flowers 12–17 mm diam.; hypanthium glabrous or pubescent; sepals narrowly triangular, 4–6 mm, margins glandular-serrate to glandular-laciniate, abaxially glabrous, adaxial pubescence not recorded; stamens 20, anthers usually red or pink, rarely white, 0.5–0.7 mm; styles 2 or 3. Pomes bright or deep red, lustrous, suborbicular, (4–)7–10(–14) mm diam., glabrous, rarely pubescent; flesh mealy or succulent mature; sepals spreading-reflexed; pyrenes 2 or 3, sides pitted. 2n = 51.

Varieties 5 (5 in the flora).

Crataegus succulenta ranges through the southern Great Lakes area to the middle St. Lawrence and southern New England, to Minnesota, to Iowa, Missouri (very rare), and Ohio, the Appalachians to North Carolina. An outlier has recently been recognized in Manitoba.

The dark twig colors of Crataegus succulenta are dramatic in winter and the coral red expanding bud scales are conspicuous in spring, more so than in most other species of hawthorn except C. macracantha. In summer, its commonly bluish green leaves, eglandular petioles, and impressed venation combine with thorn and twig characteristics to make this and C. macracantha usually instantly recognizable.

Crataegus succulenta often forms suckering thickets in the north.
