The Fascinating History of Pandanus
The history of pandanus cultivation and use dates back thousands of years. Evidence suggests that Pandanus first originated in Southeast Asia and Oceania. The earliest records of pandanus use come from:
• ancient Egypt – Pandanus leaves were found in Egyptian tombs dating back to 3000 BC
• Polynesia – Pandanus fruit, leaves and wood have been traditionally used by Polynesian cultures for centuries
• Indonesia and Malaysia – Ancient artifacts show that pandanus weaving and crafts have a long tradition
The spread of pandanus was likely facilitated by seasonal migrations of people, storms and ocean currents that carried pandanus fruit to new islands. Pandanus gradually became integrated into the cultures and cuisines of Southeast Asia and the Pacific.
The leaves and fruit of pandanus have been utilized in many ways:
• As flavoring and fragrance agents in cooking – especially for rice, breads, and desserts
• For weaving baskets, mats, hats and other crafts
• In traditional medicine to treat conditions like coughs, colds and malaria
• As building material for thatched roofs, fences and wall screening
Over time, specific pandanus species have been selectively bred for desirable traits like large leaves, sweet fruit and pest resistance. Knowledge of how to cultivate and use pandanus was passed down through oral traditions and practice.
The popularity of pandanus plants as ornamentals and theme plants has grown in recent decades, exposing more people worldwide to their intriguing history and uses.
Exploring the Various Species of Pandanus
The pandanus genus comprises over 700 known species that vary widely in form, function and geographic distribution. They thrive in tropical and subtropical regions across the globe. Some major Pandanus groupings include:
• Screw pines – Tall tree-like pandanus with prop roots that screw into the ground for stability.
• Shrubby pandanus – Small to medium-sized pandanus that form dense clumps.
• Wild pandanus – Include many fruit-bearing species with edible fruit.
• Ornamental pandanus – Cultivated for their attractive leaves and growth habits.
Some interesting pandanus species:
Pandanus utilis – Provides fragrant leaves widely used for flavoring in Southeast Asia. Reaches 30 meters tall.
Pandanus tectorius – Native to Pacific islands. Large leaves used for weaving mats, baskets. Grows up to 20 meters.
Pandanus leram – Unusual dwarf pandanus only reaches 2 meters. Texture plant valued for bonsai and containers.
Pandanus furcatus – Screw pine with thick prop roots. Furnishes fragrant fruit eaten raw or made into jam.
Pandanus martii – Beautiful shrubby pandanus with finely dissected olive green leaves. Grows 5–8 meters tall.
The diversity of pandanus species is a result of:
• Isolation – Different pandanus became separated on islands and evolved independently.
• Adaptation – Pandanus developed unique characteristics to survive diverse environments.
• Selective breeding – Humans propagated pandanus with desirable traits for specific uses.
Studying the evolution and relationships between pandanus species may yield insights about:
• Colonization of Pacific Islands
• Evolution of phenological traits (e.g. fruit, fragrance)
• Development of desirable horticultural features
Exploring pandanus biodiversity offers opportunities for discovery and cultivation of new plants with benefits for agriculture, landscaping and human wellbeing.
Cultivating and Caring for Pandanus Plants
While pandanus are relatively low maintenance plants, there are some key factors to consider when growing them successfully. Proper cultivation involves:
Sunlight – Pandanus plants prefer full sun to part shade. They require at least 6 hours of direct sunlight per day.
Soil – Pandanus grow best in well-draining soil that is slightly acidic. They tolerate poor and sandy soils but need good drainage.
Water – Water pandanus plants regularly, allowing the top few inches of soil to dry out between watering. During growth periods, water every few days.
Fertilizer – Apply balanced fertilizer to pandanus once a month during the active growing season. Use at half the recommended strength.
Pruning – Prune off dead or damaged leaves and stems to maintain an attractive shape. Some pandanus benefit from removal of old fruit stems.
Protection – Young pandanus may need protection from strong winds. Mulch around the base of large pandanus to conserve moisture.
Pests – While generally pest resistant, pandanus can be susceptible to sap-sucking insects. Ladybugs and neem oil spray provide natural control.
Propagation – Pandanus are most easily propagated from stem cuttings. Take 15–20 cm cuttings in summer, dip in rooting hormone and plant.
Diseases – Fungal diseases can affect pandanus, especially those grown in less than optimal conditions. Provide good airflow and drainage.
Caring for pandanus correctly involves balancing their basic requirements for:
• Light – Bright areas with adequate sunlight hours
• Moisture – Consistently moist but well-draining soil
• Nutrients – Timely applications of balanced fertilizer
• Protection – From extreme temperatures, wind, and pests
With proper pandanus cultivation techniques and ongoing care, homeowners and gardens can enjoy:
• Beautiful ornamental leaves and forms
• Fragrant flowers and delicious fruit (in some species)
• Natural screenings and boundaries in the landscape
• Dramatic accent plants that attract attention
