I got this Cactus in Colorado. Can someone please ID it for me, if more pics or info is needed please let me know. Thanks.
I am pretty sure it is one of the Opuntia species.
Was it growing wild in CO, or did you buy it somewhere?
Same question as Diana_K, Is it a native plant? or did you purchase it at a store or nursery, or did you get it in a trade & from what state and County?.
The reason for those questions is to help facilitate it's origin in nature which helps tremendously in ID'ing it.
And yes, please take a side view close-up of the larger spines. I have a suspicion on what it may be, but I want to be surer.
