cabbage tree that marks every wet hollow in the land
- Size
- Height: 10–20 m
- Lifespan
- 100–200 years
- Diet
- Not applicable (tree)
- Habitat
- Swamps, riverbanks, coastal cliffs, and open forest. Prefers damp, fertile soils with full sun. Tolerates waterlogging, drought, and salt spray. Often forms distinctive stands in wetlands and along stream margins.
- Range
- Found throughout New Zealand from Northland to Stewart Island. Most common in lowland and coastal areas. Also found on the Chatham Islands. Planted widely in gardens and parks.
- Endemism
- Native
- Main Threats
- Habitat loss from wetland drainage and land clearance is the primary threat. Disease (sudden decline) caused by phytoplasma has killed many trees. Browsing by livestock and possums. Climate change affecting coastal habitats.
- Population
- Populations have declined due to sudden decline disease but remain widespread. The species is common in both wild and cultivated settings. It is not considered threatened overall. Localised declines have occurred in some regions. Protection of wetlands is important for maintaining wild populations.
- Conservation Status
- Not Threatened
One of New Zealand's most iconic native trees. A tree that looks like a giant grass.
The cabbage tree has grass-like leaves and a tall, branching form that makes it instantly recognisable. Early European settlers used the leaves as cabbage, giving the tree its common name. The Māori name Tī kōuka refers to its use for food and fibre. A tree that fed the people.
A tree of the swamp and the coast. The cabbage tree grows in wetlands, along riverbanks, on coastal cliffs, and in open forest. It is extremely hardy, tolerating waterlogging, drought, salt spray, and fire. It is often the first tree to regrow after a fire, its underground stems sending up new shoots. A tree that rises from the ashes.
The trunk is soft and fibrous, reaching up to twenty metres in height, often branching into several heads. The leaves are long, narrow, and sword-shaped, up to a metre in length, forming a dramatic crown. The flowers are the story – massive, creamy-white spikes that appear in late spring, filling the air with a sweet scent. The fruit is small, white, and berry-like, eaten by birds.
The cabbage tree has been hit hard by sudden decline disease, a phytoplasma that causes the tree to die back. Thousands of trees have died, especially in the north. But the tree persists, regenerating from seed and from underground stems. A tree that refuses to give up.
To see a cabbage tree is to see a survivor. The swamp is wet. The cabbage tree stands, grass-like leaves rustling, fibrous trunk dark against the sky. The disease has killed its neighbours. It is still standing. It does not know it is a survivor. It just grows.
It has been here for millennia. It will be here as long as the wetlands remain wet.
