Stenocactus ochoterenanus is endemic to Mexico, also know as Stenocactus ochoterenanus Tiegel, Echinofossulocactus boedekerianus f. ochoterenanus Echinofossulocactus ochoterenaus Description: Stenocactus ochoterenanus is a solitary or clustering cactus characterized by numerous, acicular radial spines. The 4 central spines are usually more or less terete and the green plant body is generally obscured by the spination. It is extremely variable with one form intergrading into another, creating a taxonomic nightmare. Stems: Up to 8 cm tall, 10 cm in diameter with woolly apex; Flowers: Pale pink or pale greenish yellow, 2.5 cm long. Cultivation and Propagation: 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) - 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 5-10°C (but will tolerate -5° for short periods). The cooler temperatures develop sturdier plants and encourage the formation of flower buds.
