Candelabra Cactus
Overview
Browningia candelaris is an extraordinary, tree-like cactus species native to the hyper-arid deserts of southern Peru and northern Chile 1. Commonly referred to as the 'Candelabra Cactus' due to its characteristic branched silhouette, older specimens exhibit a unique morphology where the lower trunk is completely bare of spines, contrasting with the heavily spined upper branches.
Taxonomy and Naming
This species was originally described as Cereus candelaris in 1833. It was later placed in the genus Browningia by Britton and Rose, honoring W.E. Browning, director of the Instituto Inglés in Santiago, Chile 2.
Distribution and Habitat
It occurs naturally in southern Peru and northern Chile, specifically on the extremely dry slopes of the western Andes at elevations between 1,000 and 3,000 meters 1. Inhabiting areas of near-zero rainfall, it relies heavily on coastal fog condensation (known as camanchaca) to survive.
Appearance
This cactus can reach heights of 5 to 6 meters. The thick main trunk of mature specimens loses its spines, developing a smooth, woody yellowish-brown bark. The upper section branches out like a candelabra, bearing heavily armed stems with long, brown-to-yellow spines. Its nocturnal flowers are white to pale pink.
Cultivation
Browningia candelaris is rare in cultivation due to its extremely slow growth rate and specific demands. It requires full, direct sun, excellent ventilation, and a strictly mineral-based soil mix.
Common Mistakes
Overwatering and exposure to winter cold combined with high humidity are the leading causes of root rot, which quickly destroys the plant.

Watering
15-45 Days
Water minimally during summer; keep entirely dry in winter.
Soil
Well-draining, pumice-rich cactus mix
Strictly mineral soil, rich in pumice and coarse sand.
Safety
Pet Friendly
The upper stems bear very sharp, long spines; handle with extreme caution.
Difficulty
Hard
Expert level. Highly sensitive to excess moisture and very slow-growing.
Native Habitat
Southern Peru, Northern Chile
Found in the hyper-arid coastal deserts and dry Andean foothills, adapting to survive on mist and fog moisture.
Frequently Asked Questions
Can the Candelabra Cactus be grown in a pot?
Yes, but it grows extremely slowly and demands maximum direct sunlight along with a purely mineral cactus substrate.
How often should Browningia candelaris be watered?
In summer, water only after the potting soil has dried out completely (roughly every 15 days). In winter, withhold water entirely.
Is Browningia candelaris toxic to pets?
No, it is non-toxic, but its extremely sharp and long spines present a serious risk of physical injury to pets.
Is it possible to speed up the growth of this cactus?
Naturally, it is an extremely slow grower. Controlled watering during hot summers and very light low-nitrogen fertilizer can help slightly, but patience is key.
Where should I place my cactus indoors during winter?
Place it near the sunniest, well-ventilated, dry window, preferably in a cool room kept around 5-10 °C.
When does the Candelabra Cactus bloom?
Blooming in cultivation, especially in pots, is extremely rare. In nature, only very old, mature tree-sized specimens produce nocturnal flowers.
Why are the spines falling off from the bottom of the cactus?
This is completely natural for Browningia candelaris. As it matures, the main trunk corks over, sheds its spines, and develops a woody brown bark.
What kind of soil mix should be used?
Standard potting soils are unsuitable. Use a highly porous mixture containing 70-80% pumice, lava rock, coarse sand, and a tiny fraction of organic matter.
How can I prevent root rot?
Ensure the pot has excellent drainage holes, never let standing water sit in the saucer, and never water before the soil is bone-dry.
Can I grow this plant from seeds?
Yes, it can be grown from seed using standard cactus propagation methods, but keep in mind it will only reach a few centimeters in height during the first few years.
