We're back from a relaxing couple of days at the coast. The picture below is of a Mammillaria "ring" crest. These aren't very common. In all our years of growing cacti, this is the first one we've had...and it's a dandy. We'll be putting this up on E-Bay sometime soon, but it won't go cheap. In the meantime, I'll share a couple of photos of it...but just this one tonight. More later.
