Ok I can’t post pics on my post and I’m having difficulties posting in this comment. GET IT TOGETHER HOUZZ. Your headquarters are in Palo Alto, don’t make me come down there:)!

Echinopsis 'Rose Quartz'

Some Echinopsis maybe, like huascha?

EDIT: just saw Rob post, yeah more likely hybrid!

Sure is purty, whatever it is.

RQ was running around in HD over the last few years, I think its pretty likely, besides it looks like mine.

Here is a my Rose Quartz. Looks different than Kara's plant. Especially the spines. I took these pictures with my phone as the light was fading so quality isn't the best.

I'm not convinced Kara's is a Rose Quartz. I also agree with Alain that it's more likely a hybrid, due to those longer golden spines.

My RQ does not look like Kara’s either. Spines are different, and the flowers are red with a purplish shine. Kara mentioned in the June Blooms thread that the colour is very bright and orangish. Yes, some other kind of hybrid Echinopsis.

My "RQ" doesn't look like anyone's. I don't know if it is RQ but it is the best name I could find and that might be true for Kara too.

Laura, ‘RQ’ is a particular hybrid of what used to be called Chamaecereus sylvestrii. If your plant does not look like other Rose Quartz plants, it is probably another of the many Ch. sylvestrii hybrids. Some have names, others don’t. One of the orange hybrids is ‘Fire Chief’. To my eyes, it looks closer to Ch. sylvestrii than Kara’s plant, but I cannot find much information or pictures. Both Chamaecereus and Lobivia, the other parent of the hybrids, are now Echinopsis, so these plants are now Echinopsis hybrids ;-). Used to be Chamaelobivia. Who can keep up with plant names...

Mine is definitely not RQ, but most likely a Echinopsis/Lobivia hybrid. Funny how the tag said Trixanthocereus. Um ok;)?

My RQ and mystery cactus together.

Very different. The mystery cactus has long and short golden spines, which I have never seen golden spines on RQ, and the flower is an orange red not fuchsia. It’s really bright in person. Plus the way the MC grows is different than RQ. RQ gets new growth from the base and up and down the sides of the old growth, the way C. sylvestrii grows. So far MC’s new growth comes only from the base of the plant, similar to how most of the growth starts on my Trichocereus grandiflores.

RQ

Mystery cactus

Both cactus have been getting same strong sun and the longer RQ gets sun the more purple it gets, but the other turns more golden.

Alain, when I first looked at E. hauscha I didn’t think much of it, but on a second look there are some pics that look really close to the my cactus. I wonder if there is hauscha blood in my cactus;).

Tyler, thanks for putting up pics of your RQ because it just shows how different each one can look, and I don’t have that type of RQ. But you can see the differences between yours and the MC;).

Dinie, good info;).

Thanks everyone:)!

After all of that debate did we resolve anything? I don’t feel like we did. LOL!

Yep, its clarly not RQ. And is another Echinopsis hybrid.

MC was lookin real nice today;).

Today at Lowes for the first time since I bought this 3 years ago I saw a few little containers with this cactus in them. I got excited because maybe the id would be different, but no it said Thrixanthocereus sp.
