Houseplant of the week: Chilean dwarf torch cactus

Chilean Dwarf Torch Cactus

Why will I love it?
I’m drawn to the unique beauty of the Chilean dwarf torch cactus (Eulychnia castanea f. varispiralis), which has a blobby body that looks more like a lollipop than a plant. Its dramatic form can twist clockwise or counterclockwise, creating a unique corkscrew stem covered in striking spines.

Light or shade?
This cactus thrives in full sun or lightly shaded conditions.

Where should I put it?
A south-facing windowsill is best.

How do I keep it alive?
Water lightly in summer, allowing the soil to dry out completely between waterings. In winter, keep the cactus dry to prevent rot. Using a gritty cactus and succulent soil mix helps with the drainage. It thrives in warmth but can handle temperatures down to freezing point if the soil is dry. Monthly feeding during the growing season is essential, but it should be stopped in the winter when the plant is dormant.

Did you know?
The genus Eulychnia’s name is derived from Greek, meaning “true torch” or “candlestick”, possibly referring to the plant’s tall, slender stature. Originating in the high Andes, the Chilean dwarf torch cactus is a rare, slow-growing plant that has evolved to survive extreme drought. Its rarity, resilience and artistic form make it highly prized among collectors.
