Ponytail palm

Sun

Full sun to light shade outdoors; the brightest available position indoors, preferably with some direct sun. Acclimatise indoor plants gradually before putting them into outdoor sun.

Water

Low water needs. Let the potting mix dry out between thorough waterings, and water much less in winter; established plants in the ground need little supplementary water.

Soil

Sharply drained sandy or gravelly soil. In containers, use a gritty cactus and succulent mix and a pot with drainage holes.

Height

15-30 ft (4.5-9 m) outdoors over many years; commonly 3-6 ft (0.9-1.8 m) in containers

Spread

10-15 ft (3-4.5 m) outdoors; commonly 2-4 ft (0.6-1.2 m) in containers

Flowers

Mature outdoor plants may produce large sprays of small creamy-white flowers in summer; flowering is uncommon indoors.

Foliage

Evergreen. Long, narrow, green leaves arch and curl from the stem tips. Their finely toothed edges can scratch skin.

Growth

Slow, especially in pots or indoors.

Growth rate

Slow

• Water thoroughly, then let the mix dry before watering again; empty saucers and decorative outer pots.
• Keep the swollen trunk base above the soil surface and away from damp mulch.
• Feed container plants once or twice during spring and summer with a balanced fertiliser at half the label strength.
• Repot only when crowded, using a pot just slightly larger than the existing one.
• Keep container plants frost-free and reduce watering during cool, low-light weather.

Pruning. Remove completely brown leaves at their bases as needed, using clean scissors or secateurs. Do not shorten the trunk or trim healthy leaf tips as routine maintenance; cut leaves retain brown ends.

Spring

Check drainage and repot only if the roots or swollen base have outgrown the container.

Late spring

Once nights are reliably above 10°C (50°F), gradually acclimatise indoor plants to an outdoor summer position.

Early summer

Give actively growing container plants a light feed.

Summer

Check soil moisture before watering and inspect leaf bases for mealybugs and scale.

Autumn

In cooler climates, bring pots into bright, frost-free shelter before cold nights arrive.

Winter

Water sparingly and stop feeding; keep the plant in strong light and away from cold draughts.

• Use a single specimen in a simple container to show off its swollen base and arching foliage.
• Plant as a focal point in a frost-free gravel garden with low succulents.
• Place in a sunny courtyard where its narrow trunk and elevated foliage provide height without a dense canopy.
• Pair with stiff-leaved plants such as agaves and desert spoon for contrasting leaf shapes.

Garden styles it suits: Architectural minimal, Desert modern, Contemporary minimal, Modern courtyard, Desert / xeriscape and Small-space.

Plant it with: Blue chalk sticks, Echeveria, Foxtail agave, Red yucca, Desert spoon and Aloe vera.

Wildlife: Flowers can attract bees and other insects where mature plants bloom outdoors. Non-flowering container plants offer little wildlife value.

• Root or trunk rot: usually caused by persistent wetness, especially in cold weather. Improve drainage, stop frequent watering and remove rotted roots when repotting; a soft, collapsing trunk may not recover.
• Mealybugs and scale: inspect leaf bases and stems, isolate affected pots and treat with a labelled insecticidal soap or horticultural oil, repeating as directed.
• Spider mites: look for fine webbing and stippled leaves on indoor plants. Rinse foliage and treat persistent infestations with a labelled insecticidal soap.
• Brown leaf tips: check for prolonged drought, accumulated fertiliser salts or root damage from overwatering. Correct the cause rather than repeatedly trimming the foliage.

Not known to be toxic to cats, dogs, horses or people. No parts are recognised as poisonous, but chewing foliage can cause stomach upset, and the rough leaf edges can scratch skin or mouths.

• Madagascar dragon tree (Dracaena marginata)

  Has slender cane-like stems without the conspicuously swollen base; its narrower leaves are often edged red.

• Spineless yucca (Yucca gigantea)

  Has much broader, stiffer, sword-shaped leaves rather than long, ribbon-like curls.

• Bottle palm (Hyophorbe lagenicaulis)

  This true palm has a swollen trunk topped by a few large, feather-shaped fronds, not a fountain of undivided strap-like leaves.

The species name recurvata means curved backwards, referring to the arching leaves that also give it the common name ponytail palm.

Propagation. Usually grown from seed, sown in a warm, freely draining medium. Basal offsets can sometimes be detached and rooted, preferably when they already have roots, but establishment is slow and unreliable.

Accepted botanical name

Beaucarnea recurvata
