  Echinofossulocactus phyllacanthus
var. violaciflorus
(Syn: Stenocactus phyllacanthus)
CACTUSPEDIA       

 


A very nice form with thin needle like spines (thin spined type).


This is a very variable species, especially in the shape of the spines.
In fact i
dentifying the an Echinofossulocactus is as difficult as identifying the genus is easy.
For the most part, they tend to look alike, and there are far more names than there are species.
 


The beautiful  flowers (thin spined type)

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.
Pests: The narrow ribs, the wooly areoles, and the dense spines are an ideal habitat for mealy bugs. Frequent inspection of the plants will prevent them from spreading.
