Can someone tell me the name of this cactus? Also, how much bigger will it get? It is presently approx. 3 ft. or so.
It looks like a Pilosocereus pachycladus which can get up to over 30 feet high after many, many years if grown in the ground.
If I could see the spines more clearly, I could be more sure of which species of Pilosocereus it is.
sorry, that's not very clear, but on the back plant..notice the little leaf(?) emerging.
Nope, the spines are not the same as Pilosocereus pachycladus, neither are the ribs, so that's not it.
I'll keep looking for it though. The closeups tell me that it's highly likely to be a Cereus sp.
The second plant is a Euphorbia sp.
Someone here will know which one it is.

Notice the two spines that are pointing upwardly from the rest of spines? That's an identifying feature of this one. I looked at over 100 spine closeups and the only one I found that has those two spines pointing upward is Cereus fernambucensis. Also notice the the areolae have a small amount of wool which is also on C. fernambucensis. The only thing that dosen't look quite identical is the thickness of the branch(s) which could be either the enviromental conditions or you have a slightly different forma.
Cereus species tend to have many formas within the genus. So in my assessment, that's what it is.
Here are some other photos to compare and see the spines and wool, etc.
On this page you can see that the stems *do* get thicker like yours. And you can also see the growth habit.
I trawled through cactiguide.com & columnar cacti.com & couldn't find anything to match. I thought maybe Neocardenasia but the spines weren't a close match.
The three upward pointing spines on GAgirls picture are very difficult to match to anything
I see what you mean about Neocardinasia, check out this photo here:
Really miss Stake for this kind of cactus ID, he was really good with columnar cacti needing ID
Its definitely got a Cereus look to it though, most other columnar cacti have more ribs
Did you have any luck getting a photo with the flower open?
It should open at night and close a couple/few hours after sunrise. It's a night bloomer.
