Erect, spheric to short cylindric, 8-30 tall and 4-8 cm in diameter; ribs 10-20, crests prominent, slightly to conspicuously undulate; areoles 3-12 mm apart.
Spines: Interlocking, bristle-like slender,  typically reddish to brown (but also white or yellowish) obscuring the stems, radiating in all directions.

In culture E. russanthus is without problems and regularly shows its small  purplish flowers if we provide
an adequate winter rest period. It is sensitive to overwatering (rot prone) needs good drainage, Keep drier and cool in winter. Need full sun; Very cold resistant hardy to -20 C or less for short periods of time.
Seeds or cutting (if available)

Photo of conspecific taxa, varieties, forms and cultivars of plants belonging to the Echinocereus viridiflorus complex.
 E. russanthus is part of the E. viridiflorus compless that comprises a large number of infraspecific taxa, differing in various combinations of flower color, spine color, number and thickness of central spines, and other characters, including floral scent. Wherever such taxa are sympatric they intergrade; all are freely interfertile in the greenhouse. Among them:

  • E. viridiflorus var. viridiflorus: (Typical form) With small stems and relatively pure yellow flowers, extends from central New Mexico and the Texas Panhandle to South Dakota. (E. viridiflorus var. robustior) is a more robust form but not sufficiently differentiated and considered merely  a local variant of  E. viridiflorus v. viridiflorus.
  • E. viridiflorus var. chloranthus (E. chloranthus) with the most numerous central spines (five or more per areole), giving the plants a bristly appearance, are often considered a separate species.
  • E. viridiflorus var. russanthus (E. russanthus) : Plants with a bristly appearance usually with reddish or russet flowers. Yellow-spined plants may occur at high altitudes.
  • E. viridiflorus var. cylindricus (E. chloranthus var. Cylindricus) : The common morphotype at middle altitudes in Texas and southeastern New Mexico has 0-2(-3) central spines.
  • E. viridiflorus var. correllii  (E. chloranthus var. Cylindricus "corellii") A poorly defined, yellow-spined population near Marathon, Texas.
  • E. viridiflorus var. neocapillus (E. chloranthus var. neocapillus): Remarkable for its softly hairy, not sharply spiny, seedlings.
  • E. chloranthus subsp. rhyolithensis Bristly red-spined plants from New Mexico.

Echinocereus viridiflorus in the broad sense may prove paraphyletic with respect to E. davisii, but they are phenologically isolated, with E. davisii flowering earlier and thus appearing reproductively isolated in the wild.
