Plant Description

Identification and Physical Characteristics

Mataī ( Prumnopitys taxifolia ), also known as black pine, is a dioecious evergreen conifer endemic to New Zealand Discover more about native trees. It is a tall forest tree that can reach heights of up to 30 meters with a trunk diameter of 1-2 meters, and has an average lifespan of 600 years, potentially living up to 1000 years. The bark is thin and smooth on younger trees, developing into a dark brown to almost black colour with age, and peels freely in thick, circular flakes, leaving a distinctive "hammer-mark" pattern. Mataī exhibits profound heteroblasty, meaning its juvenile and adult forms are distinctly different. For up to 60 years, it appears as a tangled, wiry shrub with slender, flexible, divaricating branchlets and small, brown, pale yellow, or dirty white leaves. The adult leaves are dark green, linear (10-15 x 1-2 mm), and arranged spirally. As a dioecious species, male and female reproductive structures are found on separate trees. Male cones are found in spikes, while the fruit is a fleshy, oily, aromatic, purple-black drupe with a glaucous bloom, approximately 10mm in diameter, containing a single seed. These berries are a food source for native birds like the Kererū.

Proper pruning techniques help the plant direct its energy toward new growth, resulting in a more robust and aesthetically pleasing specimen in your garden.

How to Grow Prumnopitys Taxifolia

Cultivating Prumnopitys taxifolia(Zealand conifer) 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 Prumnopitys taxifoliaplants. 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.

  1. Collect seeds
  2. 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.

  1. Take cuttings
  2. Use rooting hormone

Additional Methods

Depending on the growth habit of Prumnopitys taxifolia, 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.

  1. Divide clumps
  2. 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

Mataī provided durable flooring and joinery timber and remains an emblem of lowland podocarp forests; its fruits are important to native birds and forest cycles.Prumnopitys taxifolia, commonly known as Mataī, holds significant cultural importance, particularly for the Māori people of New Zealand. Mataī wood was traditionally used by Māori for carving, building, canoes, canoe bailers, small agricultural implements, and handles, especially in areas where totara was less common. The seeds of the Mataī tree were an important food source for Māori. Various parts of the Prumnopitys plant, including Mataī, were historically used for medicinal purposes. The liquid from cracks in the heartwood, sometimes referred to as "mataī beer," was consumed to treat consumption and as an antiseptic. Mataī carries spiritual and cultural significance, symbolizing strength and resilience. It was also incorporated into traditional ceremonies and practices. Individual Mataī trees could serve as tribal landmarks and were considered to possess special powers of tapu(sacredness). A notable example is Hinehopu's tree, a large Mataī that became a significant landmark for the Ngāti Pikiao tribe.

  • Traditional medicine
  • Crafts

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

Prumnopitys taxifolia, commonly known as mataī or black pine, is a species of tree endemic to New Zealand. It is a long-lived conifer, reaching up to 30 meters in height and living for an average of 600 years, with some specimens reaching 1000 years. Despite historical logging that significantly reduced mataī-dominated forests, its current conservation status is "Least Concern" according to the IUCN Red List (assessed in 2013) and "Not Threatened" by the New Zealand Threat Classification System (assessed in 2023). However, while not currently threatened, its habitat remains vulnerable to loss and degradation due to activities like logging and land development. Very few intact examples of mataī-dominated forest remain. Conservation efforts focus on protecting mature trees, controlling pests, and restoring native forest habitats to ensure the long-term survival of this species. Individuals can contribute to conservation by supporting efforts to protect native forests, opposing activities that threaten these ecosystems, and promoting sustainable forestry practices.
