Maybe a Lobivia ferox for the first one?

The first one could be a Carnegia?

I've never knowingly seen an O.aurantiaca here either.
Not to worry, according to this 'potential distribution' prediction all I have to do is wait for it to come to me

Hence some are inclined to refer to them all as Cereus peruvianus without a second thought.
Perhaps 'Cereus domesticus' or C.urbanianus are more apt.

I agree with G.baldianum, the common one.

E.schickendantzii?

Agreed, and it's in need of a brushing or overhead watering.

But its a spineless one

I never quite understood how these two are now apparently considered synonymous under A. myriostigma.? (according to this site and desert-tropicals.com). how can they be the same species if they cannot breed with each other! (under normal circumstances). They are indeed incredibly similar but; A. co...

Unless I'm reading this wrong its actually possible to grow an Ortegocactus in a bottle of water! (nice seedlings btw Ian ).

Brilliant

Good to see they aren't all being dug up and offered on eBay by nefarious sellers.

im surprised its flowering so much, despite the lack of light.

i have seen small myrtillocactus geometrizans and harrisia jusbertii cuttings for use as grafting stocks rooted in water successfully so it surprisingly can be done. from memory it must be done in the peak of summer so the water is warm and a callous must be allowed to form beforehand, and the cutti...

Beautiful, just beautiful. The stock is good old San Pedro, so that's not a problem. yup. E.pachanoi is very cold hardy (it grows at high altitudes in the Andes), exactly how so I don't know because I don't have to worry about freezing temps here :), but it can certainly take temperatures below 0 ce...
