Plant Description
Identification and Physical Characteristics
Swamp Maire ( Syzygium maire ), also known as maire tawake or waiwaka, is an evergreen tree endemic to New Zealand Discover more about native grasses. It is found throughout the North Island and the northern half of the South Island, typically in coastal and lowland riparian forests, swamps, and stream sides, though it can also tolerate reasonably dry situations. It can grow up to 16 meters high, with a trunk up to 0.8 meters in diameter. The tree often has a smooth, pale bark that can be pinkish-grey, grey-brown, or white, and may flake in irregular shards. In waterlogged conditions, it frequently develops "knees" or erect aerial roots called pneumatophores, which are striking red breathing roots that rise from the lower trunk or exposed roots. The leaves are opposite, subcoriaceous, and typically elliptic, ranging from 15-60 mm long and 10-25 mm wide. They are yellowish-green to green, glossy on the upper surface, and paler green underneath. The leaves often have small galls, leaf blisters, or reddish spots and blotches, and their margins can be entire, sinuate, or undulate. The tree produces white, brushy flowers, about 1 cm wide, with many projecting white filaments. These flowers are arranged in cymose clusters of 5-30 flowers, which can be up to 100 mm in diameter. The main flowering period is from mid-summer to mid-winter. The fruit are fleshy, berry-like, subglobose to elliptic-ovoid, and measure 10-15 mm in diameter. They are deep crimson and glossy, containing a single large seed.

Plant Habitat
Natural Occurrence and Ecology
Swamp Maire (Syzygium maire), also known as maire tawake or waiwaka, is an evergreen tree endemic to New Zealand. Its natural habitat primarily includes coastal and lowland riparian forests, thriving in waterlogged ground, on the margins of swamps, and alongside streams.Wetland Environments:It is a specialist of wetland environments, commonly found in waterlogged ground, swamps, and streamsides. A key adaptation is the development of "breathing roots" (pneumatophores) in wet soils.Montane and Cloud Forests:It can also be found in some montane and cloud forests in Northland, the western Waikato, and the lower margins of Egmont National Park. In these areas, high rainfall and poor drainage create ideal conditions for the tree to establish itself on hill slopes, tablelands, and in karst landscapes.Moisture:It prefers wet conditions and has high moisture requirements, thriving in consistently wet or boggy soils.Tolerance:While it prefers wet conditions, it can tolerate reasonably dry situations, sun, shade, and coastal environments. However, it is frost tender and drought intolerant.Widespread:It is distributed throughout the North Island and in the northern half of the South Island, from Te Paki south to Rarangi near Blenheim.Declining Populations:Historically widespread, its populations have declined due to the clearance of swamp forests, highlighting its conservation importance.The presence ofSyzygium mairein these specific habitats underscores its ecological importance in contributing to the biodiversity and structural complexity of New Zealand's unique wetland and riparian ecosystems.

How to Grow Syzygium Maire
Cultivating Syzygium maire(Syzygium maire) is a rewarding endeavor for any gardener interested in New Zealand's unique flora. This species can be propagated through several methods, each requiring specific conditions to ensure healthy growth and establishment. Successful propagation depends on mimicking the plant's natural environment and providing consistent care during the early stages of development.
From Seed
Propagation from seed is often the most effective way to produce a large number of Syzygium Maire plants. Seeds should be collected when they are fully mature. Freshly collected seeds generally have higher germination rates than those that have been stored for long periods.
Sow fresh seeds in a seed-raising mix.
- Collect seeds
- Sow in trays
Keep moist until germination.
From Cuttings
For those wishing to replicate specific characteristics of a parent plant, vegetative propagation via cuttings is the preferred method. This technique ensures that the new plants are genetically identical to the source. Semi-hardwood cuttings taken during the appropriate season usually yield the best results for this species.
Take semi-hardwood cuttings in late summer.
- Take cuttings
- Use rooting hormone
Additional Methods
Depending on the growth habit of Syzygium maire, other methods such as division or layering might also be viable options. Division is particularly suitable for plants that form dense clumps or have spreading root systems, while layering can be used for species with trailing or flexible stems.
Division can be done in early spring.
- Divide clumps
- Replant immediately
Pests & Diseases
Generally resistant to major pests.
While generally resilient, maintaining optimal growing conditions is the best defense against pests and diseases. Regular monitoring allows for early detection of any issues, which can often be managed through cultural practices or organic interventions. Ensuring good air circulation and appropriate watering will significantly reduce the plant's susceptibility to common environmental stresses and pathogens.
Cultural Significance
Syzygium maire, commonly known as swamp maire or by its Māori name maire tawake, holds significant cultural importance in New Zealand, particularly for the Māori people. Its cultural significance stems from several uses and its role within the ecosystem. For Māori, the bark of maire tawake was valued for producing a blue-black dye, which was used for items made from harakeke (New Zealand flax). The bright red drupes (fruits) of theSyzygium maireare edible and were a traditional food source. They could be eaten raw or cooked, and were used to make "waiwaka puddings," contributing to the rich and diverse diet sourced from wetlands. Maire tawake is an integral part of the "whare-repo" (swamp home) ecosystem, coexisting with other culturally significant trees. These environments also provided other important cultural materials like paru (muds), valued in arts, rongoā (medicines), and as indicators of environmental health. The tree is known by several Māori names, including maire tawake, maire tawhake, tuhuhi, waiwaka, and whaawhaakou. Despite its historical importance, many New Zealanders today are unaware of this tree and its significance, especially given the extensive clearance of swamp forests that once covered large parts of the North and South Islands.

Bonus Tip
Excellent for low-maintenance gardens.
For an extra boost, consider applying a thin layer of high-quality organic mulch around the base of the plant. This helps retain soil moisture, suppresses weeds, and gradually improves soil structure as it breaks down. This simple step can make a significant difference in the plant's overall vigor and resilience, especially during periods of extreme weather.

Plant Conservation
Conservation Status
Syzygium maire, also known as swamp maire, maire tawake, or waiwaka, is an evergreen tree endemic to New Zealand. Its conservation status has significantly deteriorated in recent years. Previously classified as "Not Threatened" in 2012, its status was elevated to "Nationally Critical" in 2017 and then to "Threatened - Nationally Vulnerable" in 2023. Major threats include habitat loss due to extensive clearance of swamp forests and drainage of wetlands, and the devastating impact of myrtle rust (Austropuccinia psidii), a fungal pathogen. Recalcitrant seeds, which are difficult to store long-term, also pose a challenge for ex-situ conservation efforts. Conservation efforts and research are underway to protectSyzygium maire, including propagation techniques, seed banking and cryopreservation, myrtle rust mitigation, and community involvement.
