  • E. stoloniferus subsp stolonifereus: Stem cylindrical up to 30 (or more) cm tall, 5 cm in diameter with 6 radial spines. Origin. South-eastern Sonora.
  • E. stoloniferus subsp. tayopensis: Characterized by stems ovoid to shortly cylindrical stems that only get up to 15 cm tall and 6-8 cm in diameter, radial spines up to 15 mm long. Origin: Eastern Sonora, Western Chihuahua.

 

 

Cultivation: 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 -7C)
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.
