Description: Clustering specie branching profusely from the base with almost spineless stems.
The flowers on all subspecies are Bright magenta.
Stems: Up to 50 cm long, 7.5 cm in diameter, soft , cylindrical ± tapering toward the tips erect to sprawling Yellowish-green to bright green that will hold purple colour with enough bright light, During the winter rest they become wrinkled and flabby from lack of water and shrink up about 1/3 their size as they consume their stored water. With regular water they plump up quickly.
Ribs: 6-7 even non-tubrculate.
Spines: Almost spineless, the spine if present are very short, yellowish up to 2mm long.
Flowers: Magnificent magenta from the sides of the stems, short-funnellform, very large up to 10 cm in diameter or more.
Blooming seson: Blossoms in May.
Fruit: Globose, green, fleshy.
Echinocereus viereckii subspecies:
The "viereckii" subspecies has spines that are rarely longer than 2,5 cm and 6 to 9 tuberculate ribs.
The "huastecensis" subspecies has spines that are up to about 10 cm long and 8 to 13 ribs.
The "morricalii" subspecies is spineless or nearly spineless and has 6 or 7 non-tubercled ribs.
Cultivation: This cactus is widely cultivated for its flowers, it is among the easiest species to grow, flower and propagate. Indicated for full sun exposure. Water regularly from March to October. Rot prone in winter, it needs good drainage, It should be kept in a cool place during winter rest (it can briefly tolerate temp. as low as -7°C). Without this cool winter period these plants normally won't get many buds. Clustering, great for a hanging display. Stems may possibly become purple and limp in winter, but revitalize in early spring.
Propagation: Seeds or cutting.
