Native Plants, Trees and Flowers
Introduction
Across the grasslands, forests, and coastal regions of Victoria, the striking silhouette of the grass tree (Xanthorrhoea spp.) stands as both an ecological keystone and a cultural marker of deep time. Known for their blackened trunks and tall flowering spears, grass trees are shaped by fire, resilience, and long-standing relationships with Country.
For Indigenous communities across Victoria—including the Wadawurrung, Wurundjeri, and Gunditjmara—grass trees were essential to daily life, ceremony, and ecological practice. Their resin, leaves, and flower spikes were used for tools, adhesives, fire-making, and food, while their growth patterns signalled seasonal change governed through lore (Clarke 2009; Gott 2019).
On Wadawurrung Country, places such as Djilang (Geelong) and surrounding volcanic plains hold long histories of plant knowledge, where grass trees formed part of broader ecological systems connected to fire, water, and seasonal movement.
Botany and Ecology of Grass Trees
Grass trees belong to the genus Xanthorrhoea, a uniquely Australian plant group adapted to fire-dependent environments.
Key ecological characteristics include:
Fire response: Flowering is often triggered after burning
Longevity: Some plants grow only 1–2 cm per year, living for centuries
Habitat support: Flower spikes provide nectar for birds and insects
In Victoria, the most common species include:
Xanthorrhoea australis (widespread across forests and plains)
Xanthorrhoea minor (associated with wetter environments)
These plants thrive in landscapes shaped by cultural burning practices, reinforcing the connection between Indigenous fire regimes and ecological health (DEECA 2021; RBGV 2023).
Wadawurrung Country: Fire, Resin, and Cultural Practice
On Wadawurrung Country, grass trees were deeply embedded in daily life and environmental knowledge.
Fire and Seasonal Knowledge
Grass trees act as indicators of fire cycles. Their flowering following burns signals renewal of Country and the return of food resources. Wadawurrung fire practices—applied carefully across seasons—supported grass tree regeneration and surrounding plant systems such as murnong (Gammage 2011).
Fire itself is part of cultural practice tied to lore, guiding when and where burning occurs.
Resin and Toolmaking
The resin from grass trees was one of the most important natural adhesives:
Used to attach stone spearheads to shafts
Applied in repairing tools and implements
Heated and moulded for strong binding
While specific Wadawurrung terms for resin are not consistently recorded in published sources, its use is widely documented across south-eastern Australia (Clarke 2009).
Tools and Implements
Grass tree materials were used for:
Spear shafts (from straight flower spikes)
Fire drills (dry stalks used in friction fire-making)
Handles and bindings combined with resin
Across Kulin Nations, bark shelters are often referred to as wilam (meaning “home” or “camp”), and grass tree materials contributed to the broader material culture used in constructing and maintaining living spaces (Clark 1990).
Wurundjeri Knowledge: Birrarung Landscapes
For Wurundjeri people, whose Country centres on the Birrarung (Yarra River), grass trees formed part of forest ecosystems managed through fire and seasonal knowledge.
Flower spikes used as lightweight spears or shafts
Resin used as adhesive for tools
Plant cycles used to indicate ecological timing
The Birrarung itself—meaning “river of mists and shadows”—is a central cultural and ecological system, and plants like grass trees contribute to its broader health and biodiversity (VEWH 2022).
Gunditjmara Country: Fire and Landscape Systems
On Gunditjmara Country, where the Budj Bim landscape reflects complex water engineering, grass trees were part of interconnected ecological systems:
Fire management supported open landscapes for hunting
Resin and plant materials contributed to toolmaking
Growth patterns aligned with seasonal cycles linked to kooyang (eel) harvesting
These relationships demonstrate the integration of plant knowledge with water systems and food production (McNiven 2012; UNESCO 2019).
Uses of Grass Trees
Grass trees provided a wide range of practical resources:
Materials and Tools
Resin used as glue for weapons and implements
Flower spikes used as spears and fire drills
Leaves used for wrapping and shelter
Fire
Resin and dry stalks used for fire ignition and transport
Food
Nectar from flowers occasionally consumed
Insects associated with the plant sometimes harvested
These uses reflect a deep understanding of plant properties and ecological relationships.
Science and Indigenous Knowledge
Modern ecological science confirms long-standing Indigenous knowledge:
Fire ecology: Grass trees depend on periodic burning to regenerate
Chemical properties: Resin contains strong adhesive compounds
Ecosystem role: Supports pollinators and biodiversity
This alignment demonstrates that Indigenous systems of lore are grounded in detailed observation and environmental knowledge (Clarke 2009; DEECA 2021).
Colonisation and Environmental Disruption
Colonisation significantly altered grass tree ecosystems:
Suppression of cultural burning disrupted regeneration cycles
Land clearing reduced plant populations
Grazing and soil compaction damaged root systems
For Wadawurrung, Wurundjeri, and Gunditjmara communities, these changes also meant reduced access to important cultural resources and knowledge systems (Gammage 2011).
Revival and Cultural Restoration
Today, grass trees are central to restoration efforts across Victoria:
Cultural burning programs are being reintroduced
Traditional Owner groups are leading land management projects
Knowledge sharing is reconnecting younger generations with plant use and ecological practice
These initiatives reflect the continuation of Indigenous knowledge systems and their relevance to contemporary environmental management.
Conclusion
Grass trees are living markers of time, resilience, and connection to Country. Across Victoria, they supported toolmaking, fire practices, and ecological knowledge, all governed through systems of lore.
For Wadawurrung, Wurundjeri, and Gunditjmara peoples, grass trees remain part of an enduring relationship with land—one that continues despite the disruptions of colonisation.
Protecting and restoring these plants supports not only biodiversity but also the continuation of cultural knowledge and connection to Country.
