Optuntia cylindrica imbricata, commonly called "cane cactus", "cane cholla", and "tree cholla", this peculiar-looking cactus has deep roots in South American culture and ethnomedicine.
As you can see from the photos, its name "cane cactus" is very clear: after about two years, it takes on the appearance of a walking man, sometimes with an erection!

Although detailed medicinal documentation on Opuntia imbricata is limited (see references and further reading below), this species is traditionally used for burns, wounds, infections, inflammation, and gastrointestinal issues.
The word Cylindrica describes the stem and the growth form of the branches.
The word Imbricata, from Latin, meaning "overlapping edges", describes its structure, where branches grow over each other.
Although this cactus grows wild in the Iberian Peninsula, it is thought to be native to South America, brought by the conquistadors. This cactus can be found growing wild on arid plains, rocky mountains, and lightly forested conifer areas of Spain, Mexico, and the Southern United States.
THE PLANT
Imbricata is a succulent cactus, formed by a series of cylindrical sections that can grow at any angle.
As it grows, this fascinating cactus spreads by seemingly walking, setting new branches on the ground that then develop roots. Its overall form is that of a dense, medium-sized shrub. More mature plants can reach a height of about 5 meters.
This distinctive cactus is densely covered in spines that grow in clusters from a central areole. Each areole can have 18 or more spines, especially at the base of the plant, where it is most vulnerable to fatal damage. Spines can reach a length of 5 cm.
The barbed spines are covered with a papery skin. These spines easily attach to passing animals, with or without hair, thanks to the small hooks hidden by this papery sheath.
Imbricata grows in sections, or cylinders, which can reach up to 40 cm in length.
Some branches, or cylinders, grow upwards, others sideways, and others downwards. The branches that grow downwards will become its legs!
The ribs are small, ridge-shaped, and scattered along the branches. They have a tight appearance and occur in symmetrical patterns, always aligned with the direction of the branch. Like all ribs, they allow rainwater and condensed fog to flow directly to the roots, as well as providing a larger surface area for photosynthesis, minimizing water loss.
The flowers are between 4 and 9 cm and are pink to dark pink with a bright yellow center. The flowers are pollinated by insects, and are particularly appreciated by bees. Flowers appear in late spring and early summer.
This cactus produces a relatively dry, but edible, bright light orange fruit. This fruit is appreciated by wild birds and mammals, and is also safe for human consumption.
Imbricata prefers a sunny location, although it grows well in partial shade. As long as the soil drains well, this cactus tolerates temperate and arid climates, as well as Mediterranean, and temperatures from over 40 °C to -5 °C.
Imbricata is very easy to propagate by cutting a cylindrical section of the plant at its junction with the previous cylinder and placing it directly in the soil. Always remember to allow the cut end to harden before planting; otherwise, infections are likely to occur.
The cactus is ideal for creating boundaries on land. To create a border, plant it in lines approximately 1 meter apart. In 2 years, the cactus can easily "walk" a meter, thus creating an impenetrable barrier for intruders.
Imbricata requires sandy, well-drained soil with some compost. Once planted in the ground, imbricata is drought-tolerant, able to survive at least two months without water.
This cactus has a very fast growth rate; a single 15 cm branch can produce 5 or more new branches in a year.

CULTURAL IMPORTANCE
Opuntia imbricata, also known as tree cholla, holds significant cultural and spiritual importance among indigenous communities in the Southwestern United States and Northern Mexico.
The plant's resilience and unique appearance have made it a symbol of resistance and spiritual strength in arid landscapes, often associated with survival and sacred tradition.
Zuni Pueblo: The Zuni use Opuntia imbricata in ceremonial practices, reflecting its deep role in their traditional rituals and spiritual life.
Roman Catholic Penitents of New Mexico: Historically, members of this religious group would tie fresh cholla stems to their bare backs during Holy Week processions as an act of penitence, highlighting its symbolic use in religious devotion.
Despite its dangerous spines and glochids, Opuntia imbricata remains a species of cultural importance, valued not only for its physical attributes but also for its role in indigenous identity and ceremonial life.
TRADITIONAL USES
The plant's dead stems decompose into hollow wooden tubes with longitudinal grooves, which have been used as walking sticks or fashioned into curiosities, indicating their practical and artistic value.
Traditional Medicinal Uses:
Burn treatment: The Pechanga Band of Luiseño Indians uses prepared cholla to heal burns, helping to reduce scarring and accelerate healing.
Skin conditions: Among Native American groups, stems are crushed into a paste and applied to boils. The mucilaginous nature of the plant promotes wound healing and skin protection.
Earaches: The dried pith of the stem has been traditionally applied to treat earaches.
Anti-inflammatory: In Mexican ethnomedicine, roots of the Cylindropuntia species are used to treat inflammation, joint pain, flu, and stomach pain. These uses are attributed to phytosterols and other bioactive compounds present in the plant.
Urinary and digestive health: The roots are also traditionally used for urinary tract infections and stomach pain, likely due to their phytochemical content.
The main bioactive compounds isolated from Cylindropuntia imbricata and associated with its healing properties include:
Phytosterols, particularly β-sitosterol and campesterol, which exhibit anti-inflammatory, immunomodulatory, and antimicrobial activities.
Polyphenols and flavonoids contribute to the body's antioxidant control by scavenging free radicals and inhibiting lipid peroxidation.
Phenolic acids enhance the plant's antioxidant and antiradical capacity.
Alditols, such as glucitol and glycerol, identified in aqueous extracts.
These compounds support some of the traditional uses of cholla for treating inflammation, urinary tract infections, stomach pain, and flu, as well as supporting its potential in the development of immunostimulant and natural antioxidant medicines.
While specific medicinal documentation for Opuntia imbricata is limited (see references and further reading below), related Opuntia and Cylindropuntia species are widely used for burns, wounds, inflammation, and gastrointestinal issues, suggesting an overlap in traditional uses.
IN SUMMARY, Imbricata is a valuable resource for large tracts of land, useful for human health as food and medicine, and also forming a defensive barrier that creates a refuge for wildlife.
