PlantFiles: Argentine Saguaro, Cardon Grande
Echinopsis terscheckii

We have had these growing in Kingman for the last 12 years. Beautiful blooms!

This is a great cactus it grows like a Saguaro but it grows much faster, is more cold tolerant, & handles cold & moisture better. I have a 10 foot plant that has been growing in Hesperia, CA zone 8 (3500 feet) for 10 years. It has survived temperatures down to 15 degrees with little to no damage. However young plants are less cold tolerant.

I have been assured that these tricho/echinopsis type cacti *are* hallucinogenic, and down here hippies steal them from your garden. However I predict that like most alleged hallucinogens, the only reliably freaky thing youre likely to see is the contents of your stomach about 20 mins after ingestion. Wow! Why not just eat something off the footpath?

Seriously though, I have one outside in a pot suffering complete neglect and it's come through the occasional -5C withough damage. That's with really soggy conditions thrown in. So they're pretty tough.

Purchased this plant last year and have seen little to no growth. It is currently only receiving morning to early afternoon sun at its current heigth so perhaps this is the reason. It was reported to grow faster than the Arizona native but so far I have not seen it.

Beautiful and resilient large columnar cactus. Seems to handle a good amount of rain with good drainage of course. Here north of houston about 50 miles has withstood temps down to 17 degrees F for short duration without damage and in the last few months, it has been on the receiving end of record rain fall for this already high rainfall area. In the last 2 months, it has withstood nicely with over 20" of rain and is growing and looking very healthy and nice. I must add though that the bed it is planted in is built above existing groundlevel and prepared well for excellent drainage. One of my favorite cactus. Very robust and not too finicky.

This species forms an 18 inch thick trunk with age and many branches. Grows up to about 40 feet high. Flowers are white and bloom at night (another night blooming ceroid).

Nice looking cactus from ARgentina- probably pretty cold tolerant, but not sure how cold tolerant. Grows up to 20' and is exported a lot for it's skin. Not sure why, either- looks, potpoiri?.. but used to be eaten by the Indians locally. Suspect there is something hallucinigenic about it.
