Cacti at the Arizona-Sonora Desert Museum

Continuing my series of posts from our Southwest trip this summer, I’d like to take you back to the Arizona-Sonora Desert Museum (ASDM) outside of Tucson and show you some of many cacti growing there.

The most famous plant of the Sonora desert is the saguaro cactus (Carnegiea gigantea) and they are everywhere on the west side of Tucson. This is what you see as you crest Gates Pass:

Inside the ASDM, there are plenty of opportunities to see saguaros as well:

However, the most common type of cactus, both inside the ASDM and outside, is the prickly pear in its various incarnations. Judging by the number of fruits on some specimens, the blooms must have been spectacular this past spring. The fruit, often called tuna after its Spanish name, is frequently used to make jam and candy.

Opuntia littoralis (according to the plant tag but it doesn’t look much different from the
Opuntia engelmannii above)

According to the ASDM Sonoran Desert Digital Library, there are many other Opuntia species in the park but I’m not enough of an expert to identify them by sight.

Therefore, let’s move on to other cactus genera and species that were clearly labeled. That makes life much easier for lay people like me! Plus, the goal of this post is to show you the beauty of cacti, not to be an encyclopedic resource.

Similar to the Agave Garden (featured in this post), all plants in the Cactus Garden are native to the Sonora desert and the adjacent biotopes interpreted by the ASDM.

As painful as a cholla (Cylindropuntia sp.) encounter can be for a human, birds seem to have no problems getting up close, as evidenced by this nest.

I admire chollas from a distance, for the obvious reasons, but this cholla skeleton is completely harmless—and beautiful.

But the most fun cactus in the entire Desert Museum has got to be this one:

Believe me, when it’s close to 100°F, even a splash of water makes a difference :-).

  1. Some beauties there for sure, and some weird ones. I really want a totem pole cactus... wish I had a sunroom!

    I can't see photos of a cholla without thinking about the teddy bear cholla video I saw on YouTube. Not for the squeamish.

    1. That crawling Stenocereus eruca certainly would qualify as weird :-).

      You can always overwinter your totem pole cactus in the house...

      This is my favorite teddy bear cholla video on YouTube. Caution: There's some serious cursing going on :-).

  2. Wow what a great place! I love your photos Gerhard they are super and clicked on many of them to see larger. It was neat to see that cholla acting like the mother plant to that juvenile saguaro!

    1. I only photographed the plants. There are tons of animals at the Desert Museum as well: javelinas, coyotes, prairie dogs, not to mention snakes and gila monsters, a cool humming bird house, an aviary, etc.

    1. Sharon, so sorry to hear to lost all your photos. I think I'd go crazy if that happened to me. I hope my post brought back some good memories.

      I love Tucson, too. I think I could live there...

  4. What a great looking place Gerhard, Cacti porn! They're such an architectural group of plants, vicious but can imagine how lovely it must be when they're in bloom too.

  5. WOW! So Cool! A great walkabout via photo. I really can't get enough of these old growth cacti, and that photo of the montrose Lophocereus schottii, probably the best one online. I recently bought a small cutting of one at the cactus center in L.A, maybe in 20 years it will be that amazing! Thx for sharing!

    btw, the Manfreda are finally starting to wake up.
