Here is a local scop in Melbourne's suburbs
As you can see it loves the climate.. fattest one i've ever seen.

That's a real beauty. I really like the "chunkiness" of this particular species' growth habit.

I do like scops as landscaping plants; I think they're a good choice for gardeners who want to grow cacti but are put off by the spines. A kid- and pet-friendly cactus, perhaps?

Yeah I'd be interested to see what these scop x pachs look like when they mature a bit, mine are still only very small seedlings also.

I quite like the dog breed analogy, which would make even more sense if at least some of these Trichocereus species are semi-domesticated in South America.

I too think you got lots of scop and scop-pach hybrids in ozland.

And yeah, the limits of said [+more] Trichocereus species delve in other species . These are most probably a couple of species that have hybridised between them a lot

The fact that you in Ozland got many scop-pach hybrids is probably from the fact you could not import easily anything from a point and on, so you hybridised what you had, while I am not so sure scopoculica and pachanoi areas intercross in the wild....

Beautiful plant btw....

Scops tend a lot to increase/decrease their width don't they?
