i was gifted was of those cactus arrangements that are popular right now
The top layer of gravel was glued in place and I could not even chip it out with a knife No drain hole, I had to smash the plants out of their tomb Worst peat like soil imaginable. Got what soil i can off the roots . I plan to individually repot.

As some of you know I am more of an aloe guy and I am not too good with the spikeys . I imagine they are all common. Just want to look at flowers etc and decide whether to keep or gift them to others. Any help appreciated

plant 1- would guess mammillaria spinosissima


plant 2


plant 3 - Another mammillaria?


plant 4 - would guess Espostoa lanata (Peruvian Old Man Cactus)

OK here is my 60 seconds of looking at them, so I suspect Stefan will probably chime in to overrule me on some:

1. M. spinosissima 'Red Headed Irishman'
2. Echinopsis either a hybrid, or maybe calochlora (though I suspect the spines may not be quite right for that.
3. Another Mammillaria indeed, not sure which species.
4. I would say Cleistocactus strausii 'Silver Torch'

I know plant #2 after about 8 years they grow large beautiful flowers. I have a couple larger ones that produce a lot of baby plants that look exactly like that.

I think 8 years is a reflection of the conditions you are growing them in. That would be just about of flowering size over here.
