Ferocactus wislizeni (Engelm.) Britton & Rose is the correct and accepted scientific name for this species of Ferocactus. It was named and described as such by Nathaniel Lord Britton and Joseph Nelson Rose in Cactaceae in 1922. It was first named Echinocactus wislizeni by Georg (George) Engelmann. The International Plant Names Index says the name was published in Wislizeni Tour North Mexico 96. Tropicos says it was published in Memoir of a Tour to Northern Mexico in 1848 and includes Friedrich Adolph Wislizenus as the in-author. The tour was connected with Col. Doniphan’s Expedition in 1846 and 1947.
The genus, Ferocactus Britton & Rose, was also named and described by Mr. Britton and Mr. Rose and in the same publication as the species. Plants of the World Online currently lists 30 accepted species in the Ferocactus genus (as of 11-6-19 when I am updating this page). That number could change.
I brought this Ferocactus wislizeni home from Lowe’s on March 29 (2019). It was one of those “Strawflowers” from Altman Plants with the fake flower hot glued to the top. I managed to find three other cactus to bring home that didn’t have a strawflower.
The plant was in a 4 oz. (2 1/2” diameter x 2 1/4” tall) pot. The plant was approximately 1 5/8″ tall x 2 1/8” wide without the spines. The label states (along with the name being misspelled):
“Ferocactus wislizenii is native to the deserts of Texas, Arizona, Baja California, and Mexico. It is believed that the spines were used in the past as fishhooks. The flowers are variable; usually yellow to a beautiful, glowing deep orange. Protect from frost to prevent scarring.”
This plant is very small but in the wild they grow HUGE and are very long-lived (up to 130 years). They have a tendency to lean south toward the equator which apparently led to one of its common names, Compass Barrel Cactus.
Origin: Texas, Arizona, Southern California, Mexico
Zones: USDA Zones 9a-11 (20-40° F)*
Light: Sun to part shade
Soil: Very well-draining soil. Potting soil amended with pumice or chicken grit and perlite.
Water: Regular watering during the summer. Very little, if any, during the winter.
On June 8 I noticed this cactus doing something weird. For a minute I thought it was growing three apexes but I realized it was just growing. As the plant was growing taller it was producing three new tubercles at the same time. Thank goodness the hot glue stuck to the spines finally came off without any damage to the plant.
Ferocactus wislizeni has 28-30 ribs, occasionally spiraled. Ribs become less prominent with regular watering during the summer and more so during the winter with no water.
Areoles produce up to 4 central spines and 12-20 variable radial spines. This is a very small plant now, but the spines are supposed to form a dense covering and the central spines will recurve.
I had to move the potted plants inside for the winter on October 11 because an “F” was in the forecast. Most cactus can handle pretty cool temps but most of them should not be allowed to be frostbit. There are exceptions and there are many cactus that are frost and freeze tolerant. As always, I photograph the potted pants and measure the cactus and some of the succulents when I bring them inside. The Ferocactus wislizeni measured 2 1/4″ tall x 2 1/2″ wide. That’s pretty good since it was 1 5/8” tall x 2 1/8” wide when I brought it home on March 29.
I really like this cactus with its unusual ribs and the purplish color on top. I also like the prominent red color of the spines on top of the plant.
I will continue adding more photos and information as time goes by.
