Plant Description

Identification and Physical Characteristics

Mountain Tōtara ( Podocarpus laetus ), also known as Hall's tōtara or thin-barked tōtara, is a species of conifer endemic to New Zealand Discover more about native shrubs. This evergreen tree can grow up to 20 meters tall with a stout trunk that can reach 125 cm in diameter. Its bark is notably thin, papery, and flaky, which distinguishes it from the more widely known lowland tōtara ( Podocarpus totara ). Juvenile trees often have slender, somewhat drooping branchlets. The leaves are brownish-green; juvenile foliage is linear-lanceolate, measuring 3-7 cm long by 3-5 mm wide, while adult leaves are smaller, 1.5-3 cm long by 3-4 mm wide, narrow-linear to linear-lanceolate, acute to acuminate, coriaceous, and pungent, typically with a visible midvein. It produces yellow-green catkins (pollen cones) that are 1-2.5 cm long, appearing in mid-spring to early summer. The ovules are solitary or paired, developing into seeds that are green, narrow-ovoid, pointed, and nut-like, often on red, swollen, and succulent receptacles. These attractive red fruits ripen in autumn and are a food source for native birds.

How to Grow Mountain Tōtara

Cultivating Podocarpus laetus ( This resilient ) 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 Podocarpus laetus 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.

  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 Podocarpus laetus , 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

Mountain tōtara is part of the tōtara complex renowned for durable timber in traditional and colonial use. In montane forests it contributes to podocarp identity and long-lived canopy structure. Podocarpus laetus , also known as montane totara, Hall's tōtara, or thin-barked tōtara, holds cultural significance primarily among the Māori people of New Zealand, and also had uses for early European settlers. The bark of Podocarpus laetus was historically used by southern Māori to create containers called "pohatiti" for storing muttonbirds. The Whanganui Māori also favoured tōtara k tukutuku (a Māori name for Podocarpus laetus ) for canoe making because its wood was not as straight-grained and free-splitting as other timbers. Like its close relativePodocarpus totara, Podocarpus laetus wood was valued by both Māori and early European settlers for construction, including houses, fence posts, and railway sleepers. The tōtara (which includes Podocarpus laetus ) is considered a sacred tree in Māori tradition. Its widespread growth across the country and its use in crafting large war canoes (taua) contributed to its esteemed status. Podocarpus laetus was likely the first New Zealand species to be used in dendrochronological research, specifically in an investigation of Māori archaeology.

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

Podocarpus laetus , also known as Hall's tōtara, mountain tōtara, or thin-barked tōtara, is a conifer species endemic to New Zealand. It is found in montane and subalpine forests, typically at elevations between 300 and 1200 meters, and can tolerate harsh conditions like strong winds, cold temperatures, and drought. Despite historical exploitation for timber by Māori and early settlers, Podocarpus laetus is currently classified as "Least Concern" by the IUCN Red List of Threatened Species, a status maintained in assessments from 2013 to 2024. This is largely due to its extensive range and greater altitudinal distribution, which has ensured its survival over a sufficiently large area. Legal protections against logging native trees in New Zealand have also significantly reduced its exploitation. As a keystone species, Podocarpus laetus plays a vital role in New Zealand's forest ecosystems, supporting diverse communities of epiphytes, birds, and invertebrates. Its cone-fruits provide a crucial food source for native birds, which in turn help disperse its seeds. The species also contributes to carbon sequestration and forest structural complexity. While the species itself is not currently threatened, broader conservation challenges for Podocarpus species in New Zealand include limited regeneration due to deer browsing and competition from invasive species. Conservation efforts focus on protecting remaining mature forests and facilitating natural regeneration in appropriate habitats.
