Description: Clumping plant propagating using underground stolons, that forms large colonies of stems partly obscured by spines.
Stem: Upright, ovoid to cylindrical, slightly tapering toward the apex, ribbed, greyish-green to olive-green up to 15 cm tall, 6-8 cm in diameter.
Ribs: 14-16 , low and slightly tuberculated.
Areoles: Round to slightly elliptical, close set, 5 mm apart, the young ones have abundant white or brownish wool.
Central spines: 3 to 5 acicular, stiff and straight, one longer, up to 2,5-3 cm long, pointing downward in the lower part of the areole, usually brownish (or reddish, blackish or greyish).
Radial spines: 10 to 12, flattened against the stem up to 1,5 cm long darker at the tip.
Flowers: Sub-apical, short funnel-form, bright, showy yellow or whitish often turning pinkish on second day, up to 7,5 cm long and 7-10 cm in diameter.
Blooming season: Late spring, May-June.
Fruits: Red, very spiny.

Notes: Echinocereus stoloniferusSN|21769]]SN|21769]] steadily produces secondary growths by means of underground or surface stolons (like Agave, Sempervivum, etc.) and forms rapidly large clumps.

Cultivation and Propagation: In culture E. stoloniferus is without problems and regularly shows its beautiful flowers, if provided with an adequate winter rest period. It is sensitive to over-watering (rot prone), and needs good drainage. Keep drier and cool in winter. It needs to be kept in a cool place during winter rest
Without this cool winter period they normally wont get many buds.
Relatively cold resistant, (can briefly tolerate temp. as low as -7°C)
Stems may possibly become purple and limp in winter but revitalize in early spring.
Propagation: Seed, but the as stems of this cactus branches readily and soon forms a mass of shoots the simplest way to propagate it is to cut a piece of a stem (or of a stolon) in summer, let it dry for a couple of days, and pot it up.
