Last weekend I attended a plant sale at the Edison-Ford Estates. There I found this little cactus in a 4" pot. Its skin was very blue and its reddish-purple spines formed an attractive pattern. I've never seen one before and have no idea where to look in my Anderson book of cacti. Can anyone tell me what species it is and anything else about it? Thanks.

Thanks so much. Euphorbia, huh? I had no idea. It's the most cactus-like Euphorbia I've ever seen.

Yea, there are several spiny /spiky type Euphorbs. that could easily pass for some Cacti like Cereus or Chollas to a casual observer, or from a distance. Easiest way i tell smaller euphorbs like this apart from similar looking Cacti is a simple pin -prick test.. If when you poke it, little drops of milky white, latex sap weep out of the cut, it's a Euphorbia.. In some, i think the sap can be yellowish though. Regardless, it works well unless of course you catch one in flower..  

.... Beautiful, generally perfectly formed flowers, Vs. tiny flowers surrounded by colorful, alien looking Bracts..or other weird-looking reproductive parts ..is probably the most obvious difference between the two families upon close inspection... 

Interestingly, on large Euphorbia, if the the outer layer of each rib of an individual stem gets damaged in a freeze, it may kill the plant, or the specific stem. Or so i'd heard a couple times in the past.. With most Cacti, if a rib gets damaged, it can heal itself off, and not sacrifice the entire plant ..
