Ferocactus emoryi is spherical or cylindrical solitary barrel cactus, light green to glaucous, reaching a diameter of 60–100 centimetres (24–39 in) and a height of 2–2.5 metres (6 ft 7 in–8 ft 2 in). It has 15 to 30 ribs with tubercles, especially in the juvenile stage. The spines are white to reddish. The central spine is very strong, 4-10 cm long, while the seven to twelve radial spines reach lengths of up to 6 cm. The large and funnel-shaped flowers are usually red or yellow, reach lengths of up to 7.5 centimeters and have a diameter of 5 to 7 centimeters. The fruit is ovoidal, about 5 cm long.
Ferocactus emoryi grows in the desert scrubs, hillsides, rocky slopes and gravely rocky or sandy soils, at an elevation of about 0–1,200 metres (0–3,900 ft) above sea level.
