Myrtillocactus geometrizans

I've had this guy since the beginning of 2014. It's a fairly slow grower, but has a beautiful blue green hue. The spines, although small, are very pointy and should be avoided! That's as it should be thought because when the skin of the plant is touched, the powdery substance rubs off, and the overall look of the plant becomes a bit diminished.
