Q.Mystery Cactus

Zone 48135 | ThornyRose068 added on April 3, 2018 | Answered

Hi! I bought a cactus a while back, and I haven’t been able to find out what it was. It’s about 4″ tall, and its spines are about the size of sewing needles. Does anyone know what this is???

Although it will be nearly impossible to point out the exact identity of this... I can say without a doubt that it is a type of euphorbia. As to which variety, this will be hard to tell. These will have a very similar care to the crown of thorns type of euphorbia, but is technically more of the cactus variety, so you can get away with less water than a crown of thorns. I will include articles for both crown of thorns care, and cactus type euphorbia care, and you can care for it with a combination of the two. They are very forgiving, and will tolerate conditions outside of their comfort.
