Native to deserts and dry regions of the Americas, cacti are succulents at their simplest: a water-storing body and vestigial leaves (spines). These radiate from growth points called areoles, don't photosynthesize---the green body of the plant does that---and they fend off thirsty predators.
Cacti are amazing. Imagine trying to fashion an object that retains moisture despite arid conditions, withstands temperatures upwards of 100 degrees F and below freezing, and doesn't disintegrate under ultraviolet rays. What would it be made of? Glass, plastic, metal or wood? None have a chance. Now, consider that this desert object also grows and reproduces!
True, cacti can be difficult to garden around. But you can easily grow and enjoy small specimens in pots. Give them full sun for most of the day (in all but the hottest climates) and water sparingly. Be sure you have the right tools when it comes time to transplant them.
I'd rather photograph cacti than any other plants. Flowers are big and bright and shapes are intriguing. Spines form patterns and glow when backlit.
Because "cactus" deserves a gentler name, I've come up with "halo plants." That's yet to catch on, but cacti themselves certainly have. You too may find that an appreciation for these succulents' simple, sleek, sculptural forms is a natural progression. Is it any wonder that cactus collectors number in the millions worldwide?
Cacti and euphorbias don't really work, at least for the long-term, in floral-style succulent arrangements. Although they do add contrast and texture, most cacti (tropical varieties are an exception) have different light-and-water needs compared to soft-leaved succulents. So, plant the spikies in their own pots.
These globular cacti, from my Cactus Curio Box project, are readily available in nurseries and online. For more cactus varieties and IDs, scroll to the gallery. The plants' botanical names are there and in the post.

When profiled by Garden Design magazine, I took the opportunity to come out as a cactus lover. Well, I had to. They asked about trends in the world of succulents. I believe my progression is fairly typical. Most of us start out loving succulents that look like fleshy roses—echeverias, graptoverias and the like. As people gain appreciation for the…
Cacti are succulents with simple shapes, and none illustrate the plants’ elegantly elemental geometry as well as spherical varieties. To showcase the beauty of these often-ignored succulents, I went with an open wood box with a dozen partitions, each just right for cacti in 2.5-inch pots. My goal was to elevate textural, glowing orbs to the status of jewelry or artwork.
