Could it be a Pilocerus alensis? There are so many that look similar.

Thanks! I was also told it could be the blue cactus. I have never seen it go blue. not even in the summer in full sun. it's a mystery for now. I'll let it keep growing. I believe these varieties don't flower for many years? The taller cactus.

We too.

I'm not an expert, but if I had to take a SWAG to have a chance of winning a contest, I would say Echinopsis for genus and stretching things even more, bridgesii for the species ( Bolivian torch ).

Not saying I'd win the contest so, don't bet your life on it. :^)

Yes Bill. you're on the right track. Echinopsis terscheckii

Kyle, I'd like you to leave me alone, you're making me very uncomfortable. Go away. Now people get a sense of how you are creep.

Matt,

South American columnars are a difficult lot to ID when they're that young, for the most part. Until it's flowering or it's older (both), I'd hesitate to assign a binomial to it.

Maybe it's just the way the picture looks but it appears that the pot media consists mainly of peat and possibly will stay too moist for a period.

What you want a good draining media that gives the roots a chance to dry for a time, otherwise various pathogens can start up in the roots and at the base.

It's been good for a year or more now in this pot...same soil. I had just watered it. it's stays dry over the winter getting water once a month

That's the main thing, you just have to watch it and not overwater.

Picked these up today.. (houzz.com)

not sure if this link will work. second pic is when I got it.. it was tiny.. so yes 3 years old.

Worked well. Took me right to your older post. :-)

I really like the opuntia and have always thought about getting one with a saguaro appearance.
