About Queen of the Andes
Puya raimondii · also called Royal Bromeliad, Giant Puya · tropical
The world's largest bromeliad, native to the high Andes of Bolivia and Peru, forming a massive rosette of spiny leaves that can take decades to bloom. It thrives in bright sun with excellent drainage and cool nights. Not individually listed by the ASPCA but spiny leaves pose physical injury risk.
Preferred mix: Very free-draining gritty mix — cactus/succulent blend with added perlite or coarse sand
Watch for — Root rot: Caused by overwatering or poorly draining soil; allow soil to dry thoroughly between waterings and use a gritty mix.
Why queen of the andes needs this mix
Queen of the Andes is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Queen of the Andes is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons queen of the andes struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates queen of the andes's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for queen of the andes.
