Trichocereus ...?

[widea]

Hi,

Both cacti should be Echinopsis/Trichocereus Pachanoi but I have my doubts about the one on the right. That one looks more like Echninopsis/Trichocereus Peruvianus, correct?



Thanks!

The one on the right looks like a myrtillocactus geometrizans or maybe some kind of stenocereus.

I understand your suggestion of Myrtillocactus geometrizansis regarding the shape but the color does not match, not blue/green and the spines are not dark/black.
I still suspect it to be Trichocereus, maybe I'll have to wait until it has grown bigger to see if and how it branches.
A view from above:

The top down view makes me think trichocereus bridgesii or maybe even peruviana but something about it does not look right for either. It could even be a hybrid.

The spines do not seem long enough for bridgii. Maybe peruvianus or as you suggest, a hybrid.

I think the one on the right is Trichocereus bridgesii. The spines probably aren't long enough because of the amount of light it receives.

Pachanoi & Bridgesii

In one week I will put it outside so it gets more light. I'll see if the spines grow longer then.
For now it receives a temporary label 'bridgii'. Thanks!

Looks very similar to my young T. bridgesii.

If it is older and bigger (and I can keep it alive/growing in this Dutch weather) I will post another photo.

For what it is worth, here is a Trichocereus peruvianus growing in my front yard. Sorry for the picture quality, it is a snapshot taken with an old camera. The plant had attained a height of approx ten feet (3 meters) but we had to cut it back to comply with our Homeowners Association plant height rules:

Out of interest how old is that one James? I got a peruvianus and would like to know quick they grow.

FWIW here's one that shows growth over one season

Thanks for that nona gives me an idea what to expect. I think I will give it a bigger pot and a richer soil too. I think they do grow better with more organic soil.
