🌴 Hyophorbe lagenicaulis

Hyophorbe lagenicaulis, commonly known as the Bottle Palm, is an extraordinary tropical palm from Mauritius, celebrated for its distinctive bulbous, bottle-shaped trunk and elegantly arching fronds. The thickened base acts as a water reservoir, giving the plant its iconic silhouette and excellent drought tolerance once mature.

It is a slow-growing palm, typically forming a single grey trunk that swells near the base and narrows towards the crown. The foliage consists of 4–6 long, feather-like fronds with leaflets that curve gracefully downwards, creating a poised and tropical look. In its native climate, the Bottle Palm may reach 3–4 metres, but in containers or cooler climates it remains much smaller and compact – perfect for conservatories, heated greenhouses, or tropical-themed interiors.

This rare and striking species makes a bold architectural statement, valued both for its sculptural form and exotic appeal.

🛠️ Hyophorbe lagenicaulis – Comprehensive Care Guide

🌞 Light Requirements

• Requires bright, indirect light to full sun.

• Indoors: best placed in a sunny conservatory or near a south- or west-facing window.

• Outdoors in summer: can be placed in a sunny, sheltered patio.

• Avoid deep shade – inadequate light will reduce frond production and slow growth.

💧 Watering

• Keep soil moderately moist, especially during the growing season (spring and summer).

• Water when the top 3–5cm of soil feels dry.

• In winter, reduce watering to every 2–3 weeks, ensuring the plant never sits in soggy soil.

• The swollen trunk provides some water storage – overwatering is a greater risk than underwatering.

🌫️ Humidity

• Prefers moderate to high humidity (50–70%).

• In dry indoor air (especially in winter), increase humidity by:

  • Using a humidifier,

  • Placing a pebble tray with water beneath the pot,

  • Light misting around the foliage – avoid wetting the crown directly.

🌡️ Temperature

• Thrives in warm temperatures: 18–30°C ideal.

• Very frost-sensitive – never expose to temperatures below 10°C.

• Must be overwintered indoors in the UK – a heated greenhouse or conservatory is best.

• Protect from cold draughts and sudden temperature drops.

🌱 Soil

• Requires free-draining, sandy or gritty soil.

• Best in a mix of:

  • 2 parts loam-based houseplant compost,

  • 1 part coarse sand or perlite,

  • 1 part orchid bark or horticultural grit.

• Drainage holes are essential to prevent root rot.

🍽️ Feeding

• Feed every 4–6 weeks in spring and summer with a balanced palm fertiliser.

• Reduce feeding in autumn and do not feed in winter.

• A trace element-rich feed (with magnesium and manganese) will help maintain leaf colour and prevent frond yellowing.

✂️ Pruning & Maintenance

• Minimal pruning required.

• Remove fully dead or damaged fronds at the base using clean secateurs.

• Never prune green fronds or the central spear – damage here can be fatal, as palms grow from a single terminal bud.

🪴 Repotting

• Repot every 2–3 years, or when rootbound.

• Use a deep pot with a wide base to accommodate the swollen caudex.

• Repot in spring for best results.

🐛 Pests & Problems

• Generally pest-resistant, but may occasionally attract:

  • Spider mites or mealybugs in dry indoor conditions,

  • Scale insects on undersides of fronds.

• Frond yellowing can indicate:

  • Overwatering,

  • Nutrient deficiency (especially magnesium),

  • Cold exposure.

☠️ Toxicity

• Not known to be toxic to humans or pets.

• Always supervise pets around rare or valuable tropical specimens.

🌟 Top Tips for Success

• Perfect for indoor palm lovers who want something unusual and sculptural.

• Grow in a large, decorative container to highlight its elegant form.

• Combine with ferns, Alocasias, and other warm-climate tropicals for a lush display.
