Pediocactus simpsonii, our Mountain Ball Cactus, blooming in a park south of Denver. This is the best specimen I’ve ever seen. These were more numerous before poachers depleted their number. Overseas interest in our cacti drives this threat. #nativeplants

The snowball cactus — Pediocactus simpsonii

I was quite pleased to see this blooming today at Denver Botanic Gardens. As I wrote the Wikipedia article on the species.

Sollte es kein #Aprilscherz sein, würde ich Botaniker Prof. Dr. Pierre Ibisch zum Berufswechsel raten, denn #Pediocactus braucht gar keinen #Klimawandel, um in #Deutschland wachsen zu können, nur sandigen, nährstoffarmen Boden. Temperaturen zwischen -20°C und +40°C hält diese Kakteenart gut aus! 🌵🤷🏼‍♂️

The photo of the Mountain Ball Cactus I originally posted was in full sun. I took this photo of the same cactus once it had clouded over- interesting how different the colors are...

I stumbled upon this most extremely perfect Mountain Ball Cactus last week, and realized it would be rude not to share this incredible beauty with you!

One of my favorite places is just a few miles west of the Columbia in Kittitas Co, and these photos are from last May. I first found my way out there seeking out Pediocactus nigrispinus (basalt cactus), a sensitive population in Washington

The plant in my cover photo is my favorite cactus native to Washington state! Pediocactus nigrispinus grows high up on the semi arid ridge tops in central Washington. They can be difficult to locate, but another benefit of the large wind farms nearby is providing protected habitat for these gems!

This is a Cochemiea species (formerly part of Mammillaria). Pediocactus simpsonii doesn't occur in Arizona, and especially not in the Sonoran desert.
