Plant Description
Identification and Physical Characteristics
Mountain Tōtara ( Podocarpus nivalis ), also known as snow tōtara, is a species of conifer endemic to New Zealand Discover more about native ferns. It typically grows as a prostrate or sprawling shrub, usually 20-40 cm tall with spreading branches, but can also be semi-erect and reach up to 2 or 3 meters in height. Branches that touch the soil often root, allowing it to form mats several square meters wide. The leaves are thick, rigid, and closely spaced, arranged spirally around the branchlets. They are generally 3-10 mm long and 2-2.5 mm wide, boat-shaped to ovate-linear, and can be brownish-green, dark green, bronze-green, or sometimes dark wine-red or bronze-purple, especially as they age. The leaves have distinctly thickened margins and a prominent midvein. It is found in the North and South Islands of New Zealand, typically in subalpine to alpine scrubland and tussock grassland at elevations ranging from 800 m to 2,500 m above sea level. It is known for its hardiness, capable of withstanding temperatures as low as -25 °C and surviving long periods under snow. The plant produces succulent red arils, which are edible and have a sweet but resinous flavor.

How to Grow Mountain Tōtara
Cultivating Podocarpus nivalis ( Podocarpus nivalis ) 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 nivalis 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 Podocarpus nivalis , 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
Snow tōtara's naturally compact form makes it a favourite for rock gardens and alpine collections, showcasing the adaptability of New Zealand podocarps from lowland forests to high country.While specific traditional uses for Podocarpus nivalis are not widely documented, other Podocarpus species, particularly the tōtara, have been historically utilized by the Māori people of New Zealand for medicinal applications and for wood in building and carving. Podocarpus nivalis , also known as snow totara or mountain totara, is a conifer endemic to New Zealand. Its berries are reportedly edible but are not particularly palatable and are considered more of a survival food. The plant is primarily valued today as an ornamental evergreen shrub or groundcover due to its slow growth, compact habit, and hardiness. It is also used for erosion control and is deer-resistant.
- 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
Podocarpus nivalis , commonly known as mountain or snow tōtara, is a conifer species native to New Zealand. It is currently classified as "Least Concern" (LC) on the IUCN Red List of Threatened Species. This conservation status is attributed to its widespread distribution across the highland regions of New Zealand and the fact that it has not been significantly impacted by deforestation. The population of Podocarpus nivalis is considered stable. It thrives in montane to sub-alpine environments, frequently found in open grasslands and scrublands. Although localized erosion caused by overgrazing from livestock or introduced deer may lead to declines in certain areas, the species is protected within several national parks. Additionally, Podocarpus nivalis is cultivated as an ornamental shrub.
