Ponytail Palm
Beaucarnea recurvata · the Elephant's Foot
It grows on dry, rocky slopes in eastern Mexico, surviving long droughts. Despite the name it is not a palm. It is a relative of asparagus that stores water in a fat, swollen base, and in its tiny homeland it is Critically Endangered.

Where it's from
Eastern Mexico
Dry rocky slopes
Low deciduous forest on poor, rocky soils, where the dry season is long.
Outdoors: zones 10–11
Frost-tender. A summer patio plant at most; it must come inside before frost.
Critically Endangered
Hunted in the wild for the very seeds that fill garden-centre shelves.
The water-storing belly
The swollen, flask-shaped base is a caudex, a reservoir the plant fills with water to survive months of drought. It runs CAM photosynthesis, the same water-thrifty trick as cacti, opening its pores at night to lose less water. The fountain of leaves on top is what earned it the ponytail name.
Not a palm at all
It is a member of the asparagus family, not a true palm.
A desert survivor
The stored water in its base lets it shrug off long stretches of neglect.
Slow and reluctant
It rarely produces offsets, so almost every plant in trade is grown from seed.
How to keep it
LightBright to full sun
Grows best in bright light and tolerates some direct sun. Stretches and pales in shade.
WaterOnly when bone dry
The caudex stores water, so let the soil dry right out. Soggy roots are the number one killer.
HumidityDry air is fineLow humidity, no misting. It came from semi-desert.
TemperatureWarm, above 10°CKeep it frost-free; it is not cold-hardy.
SoilCactus / succulent mixSandy, gritty and fast-draining, never water-retaining.
FeedingBarelyA light feed once or twice in summer is plenty.
DifficultyEasiest there isA near-bulletproof beginner and desk plant that thrives on neglect.
With petsSafeNon-toxic per the ASPCA, though the tough leaves can cause mild stomach upset if chewed a lot.
PropagationSeed or offsetsSlow from seed; root basal pups when it produces them.
RepottingRarelyEvery few years. It is happy left a little pot-bound.
What the data says
What it costs
Common and cheap in small sizes. Old, thick-based specimens are the expensive ones.
$10–40
Large, thick-caudex plants run well over $100, and variegated forms like Gold Star carry a premium. No collector bubble.
IUCN · Critically Endangered
In the wild
The sharpest contrast in the houseplant world: unkillable on a desk, vanishing in its homeland.
Assessed Critically Endangered in 2019, with a decreasing population, and listed on CITES Appendix II. Habitat loss and the illegal collection of wild seeds and seedlings for the ornamental trade are the threats. The pot is thriving; the homeland is not.
When it sulks
Soft, mushy baseOverwatering and rot, by far the most common cause.
Brown leaf tipsDry air, salts in the water, or inconsistent watering.
Yellow, limp leavesUsually too much water.
Pale, stretched crownToo little light. Move it somewhere brighter.
PestsSpider mites, mealybugs and scale. Wipe the leaves, treat early.
