Pygmy date palm
Phoenix roebelenii
In other languages: Dwergdadelpalm (Nederlands) · Palmier dattier nain (Français)
The pygmy date palm (Phoenix roebelenii) comes from South-East Asia, including Laos, where it often grows near water. It is a graceful palm with a single slender trunk and a crown of softly arching, glossy dark green, feathery fronds of 60–100 cm. It grows slowly and reaches about 2 m indoors. It is related to the true date palm but stays much smaller and has sharp spines at the base of the leaf stalks. As a houseplant it is a classic that immediately gives a bright corner a tropical feel.
Caution: Beware of the long, sharp spines at the base of the leaf stalks: they can prick and cause small wounds. Wear gloves when repotting and pruning and do not put the plant in a busy walkway or in a young children’s play corner.

Identify
Pygmy date palm: how do you recognise it?
- Growth habit
- Slow-growing palm, usually with a single slender trunk, about 2 m tall and 1.5 m wide indoors.
- Fronds
- Feathery, 60–100 cm long and gracefully arching, with narrow, soft, glossy dark green leaflets.
- Trunk
- Slender and brown, marked with scars of fallen fronds.
- Flower and fruit
- Small, creamy-white flower clusters on separate male and female plants, rarely indoors. Small purple-black fruits of about 1 cm.
- Spines
- Long, sharp spines at the base of the leaf stalks (modified leaflets).
Plants: April–May
In your garden
Why grow it?
- A graceful, feathery crown that gives any bright corner a tropical feel.
- Stays small for a palm and grows slowly, so it fits the same spot for years.
- Tolerates sun and a bright spot better than many other houseplants.
- Evergreen and fairly easy to look after.
- Lovely as a specimen in a large pot, and on a sheltered terrace in summer.
Pygmy date palm: where does it grow best?
- As bright a spot as possible: a south-, east- or west-facing window with a few hours of sun, or light half shade. In low light the fronds become long and floppy.
- Free-draining palm or potting compost with about a fifth of sand or perlite; acid to neutral.
- Warm: 18–28 °C in summer, 12–18 °C in winter. Never below 10 °C.
- A sturdy pot with drainage holes and room around the plant, out of draughts and away from radiators. Allow for the spines.
- Light
- Sunny or bright, out of direct sun
- Potting soil
- Multi-purpose compost or airy, humus-rich compost
- Acidity
- Acid or neutral
- Watering
- Moderately
- Size
- 2 m tall, 1.5 m wide
- Temperature
- Minimum 10 °C
Goes well with
- Dragon tree (Dracaena): The same bright spot and a sturdy, upright shape.
- Yucca: Also loves plenty of light and drier compost.
- Bird of paradise (Strelitzia): Large, tropical leaves next to the fine feathers of the palm.
- Elephant bush (Portulacaria): A sunny spot and sparing watering, like the palm in winter.
Maintenance
Pygmy date palm: when and how to plant it?
Plant in April–May.
- Repot in April–May and only when the roots fill the pot, usually every 2–3 years: palms do not like their roots disturbed.
- Wear gloves: the spines on the leaf stalks are sharp.
- Choose a sturdy pot with drainage holes, one size larger, and put a layer of clay pebbles at the bottom.
- Use palm or potting compost with a fifth of sand or perlite for a free-draining mix.
- Set the plant at the same depth as before, fill in and firm gently. Water and keep it out of strong sun for the first few weeks.
Care
- Water
- Keep the compost lightly moist in summer: water as soon as the top 2–3 cm are dry, until it runs out of the holes, and empty the saucer. Less in winter: the compost may dry out further. Never leave it standing in water.
- Feeding
- From April to September every 2–4 weeks, half a dose of palm or houseplant feed. Not in winter.
- Light
- It tolerates some sun, but get it used to it gradually. Turn the pot now and then for an even crown.
- Humidity
- It likes slightly more humid air. A tray of clay pebbles or an occasional mist helps, especially in a heated room in winter.
- Fronds
- Dust the fronds with a damp cloth or rinse them in the shower. Wear gloves.
Tip: Put it in the brightest spot, with a little sun if you like, and keep the compost lightly moist in summer and drier in winter. Wear gloves: the spines at the base of the fronds are sharp.
Pygmy date palm: when to prune it?
When: A palm is not pruned into shape. Cut off only fronds that are completely brown and dry, at any time of year.
How:
- Wear gloves because of the spines.
- Cut off only completely brown, dry fronds, close to the trunk, with clean, sharp scissors.
- Do not cut off green or half-green fronds: the palm still draws nutrients back from them.
- For a single brown tip, cut off just the tip and leave the green part intact.
Caution: Do not damage the growing tip in the heart of the crown: a palm without its growing tip forms no more new fronds.
Propagation
- Seed
- Palms cannot be grown from cuttings, and division is rarely possible with this species. Sow fresh seed in spring: 1–2 cm deep in moist, sandy seed compost at 25–30 °C and in the light. Germination is slow, often 2–3 months or more; pot on seedlings only when they have a few leaves.
Pygmy date palm: how does it get through the winter?
- Not hardy: the minimum temperature is 10 °C. It overwinters indoors.
- Put it in the brightest spot and keep it cool (12–18 °C), away from radiators and draughts.
- Water much less: the top layer may dry out further, but never the whole rootball. Do not feed from October to February inclusive.
- The air in a heated room is dry: watch out for spider mites (see Problems).
Diseases and pests
- Brown leaf tips: Dry air, hard water, too much or too little water or salt build-up. Use rainwater, flush the compost through and cut off only the brown tip.
- Spider mites: Fine webbing and pale fronds in dry air. Shower the plant, raise the humidity and repeat; cut off badly affected fronds.
- Scale insects and mealybugs: Brown shields or white fluffy patches on the leaf stalks and between the fronds. Wipe them off with a cotton bud dipped in soapy water and repeat weekly.
- Yellow lower fronds: Old, lower fronds turn yellow naturally, but a lot of yellow means too wet, too dark or a nutrient shortage. Adjust watering and light and give a palm feed.
Through the year
- January: Rest: bright, 12–18 °C, little water.
- February: Rest. Watch for dry heating air and spider mites.
- March: More light. Slowly start watering a little more again.
- April: Repot if needed (wearing gloves). Start feeding.
- May: Repotting still possible. Growth: water regularly. From mid-May you can acclimatise it outdoors in a sheltered spot.
- June: Growth. Water regularly, feed every 2–4 weeks.
- July: Growth. Check for pests.
- August: Growth. Keep feeding.
- September: Last feed. Bring indoors when it turns cooler.
- October: Indoors before nights fall below 10 °C. Water less.
- November: Rest: bright and cool.
- December: Rest. Keep away from radiators.
You and this species
Did you know?
- It belongs to the same genus as the true date palm (Phoenix dactylifera), but stays much smaller.
- The species name roebelenii honours Carl Roebelen, a plant collector who made the palm known in Europe.
- There are male and female plants: only female plants bear fruit, and indoors that rarely happens.
