Echinofossulucactus kellerianus
(Syn:  Stenocactus crispatus )
CACTUSPEDIA       

 


The upper spine spines are long flat and straight.
 



 
Description: Usually solitary round or flat
Stem:
Up to 7 cm broad, 4 cm highly; Vertex woolly;
Ribs: approx.. 60, rather hard;
Spines: Ferocious-looking, Radials 2-4, to approx 5-20 (30) mm long, light brown; with one stronger  upper one approx. 1 to 4 (5,5) cm long, 1.5-3 mm wide, yellowish-white-grey with darker tip;
Flowers: 2.5 cm broad; tepals inside purely white, with violet centre strip.

Cultivation:
Easy to to care and flower. No absolute schedule can be given for watering as  various factors (Soil mixture, containers, drainage, temperature, size of plant) influence water use, so  - as a general rule - the soil should be thoroughly wetted at each watering during the active growing season (spring and summer), water when the top 1,5- 2 cm of soil feels dry to the finger. Do not soak the soil during the dormant period. Be careful, excessive watering can make root and/or stem to rots. Make sure there is good air circulation between plants.
Good drainage is essential along good moisture retention properties and adequate nutrients availability.
Require bright sunlight to grow well.
Dormant plants do best at temperatures from 5-10C (but will tolerate -5 for short periods). The cooler temperatures develop sturdier plants and encourage the formation of flower buds.
 

Propagation: seeds, cuttings, or offsets (if available). Allow cuttings to dry for a few days before placing in a rooting medium. This permits the cut surface to heal, or callus. The callus helps prevent rotting when the cutting is placed in the rooting material.
