They are funnelform in shape, up to 3.5 inches long with dark-green stigmas. The fruit is very spiny. At first it is green, becoming pink and drying when ripe. The ripe fruit has spines which are easily detached. The seeds are black, and around a tenth of an inch in size.
The stems are initially cylindrical and erect in young plants, but later with the stem base lying on the ground. The stems are usually 1.5 to 3.5 inches in diameter and up to 25 inches high, and obscured by heavy spines. The plants have around 10 ribs, which are somewhat flattened and tuberculate.
Spines variable in color and size.

Radial spines are shorter and needlelike, up to 0.8 inch long, white and arranged in a neat rosette. Central spines number 2 to 7 and are stout, usually twisted or angular, up to 3 inches long and variable in color: bright yellow, dark brown, grey, and white.
Echinocereus engelmannii is commonly used as a landscape plant in its native areas. In pot culture it requires well aerated gritty substrate, and a hot and sunny location in the summer. In the winter the plant easily tolerates light frost and wet (if well-drained) soil. In cultivation it usually does not bloom until it develops 2-3 branches.
