Echinopsis ancistrophora ssp. arachnacantha

Origin:  Bolivia

Light:  Full Sun

Water:  Moderate



 

__________________________________________________________

This subspecies of ancistrophora takes it's name from the spider-like appearance of the recurved spines.  This Bolivian cactus has yellow flowers and usually produces many offsets.

Echinopsis chamaecereus 

Peanut Cactus

Origin:  Argentina

Light:  Full Sun

Water:   Moderate

________________________________________

Echinopsis chamaecereus or the Peanut Cactus is an attractive and easy to grow specimen.  Flowers come in different colors, depending on the cultivar.

Offsets readily detach or roll away on their own to start new plants.  The spines of the Peanut Cactus are softer than most making this a great beginner cactus.

 

 

 

 

Echinopsis pachanoi (Trichocereus pachanoi)

San Pedro Cactus 

Origin:  Ecuador/Peru 

Light:  Full Sun

Water:  Moderate

__________________________________________________________

Commonly known as the San Pedro cactus, e. pachanoi is a popular columnar cactus.  Most plants have short and inconspicuous spines and green to blue green colored skin.  The growth rate of this species is impressive.

The San Pedro cactus can be propagated via cuttings or seed rather easily and can even be used as grafting stock for slower growing cacti.

This cactus is one of the more revered cacti for the indigenous peoples of the Americas.  Mescaline and other psychoactive alkaloids can be found in significant concentrations depending on the individual plant.  Growing or owning the San Pedro is perfectly legal, however production/preparation with the intent to consume is not.


Echinopsis pentlandii

Light:  Full Sun

Water:  Regular







Echinopsis terscheckii

Cardon Grande

Origin:  Argentina 

Light:  Full Sun

Water:  Regular



__________________________________________________________

This cactus forms a large branched column over time.  The photo here is of a young specimen and can be thought of as a mere seedling compared to it's larger adult form.  Mature plants are look like they are straight out of a western film, much like the Saguaro cactus.

In my experience, this plant can handle regular watering - readily taking in what moisture is offered.  The spines on this Echinopsis are long and fierce, penetrating most types of gloves with ease.
