Pua O Te Rēinga

Dactylanthus taylorii

Not specified

Last updated:

Dactylanthus taylorii, known to Māori as Pua o te Reinga, is New Zealand's only fully parasitic flowering plant. It lives almost entirely underground as a woody tuber up to 50 cm across, attached to the roots of native host trees such as fivefinger and broadleaf. As it grows it deforms the host root into a fluted, rose-like shape, earning the name Wood Rose. Only the dense, reddish-brown inflorescence pushes above ground to flower, releasing a strong musky scent that attracts its main pollinator, the native short-tailed bat. It grows in lowland and montane forest and is very slow-growing and long-lived. Explore more native flowering plants in our native plant guide.

Plant Description

Identification and Physical Characteristics

Dactylanthus taylorii lives entirely underground, forming a tuberous, woody stem up to 50 cm in diameter, which attaches to the roots of various native host trees (e Discover more about native trees.g., Fivefinger, Mingimingi, Broadleaf). Its common name "Wood Rose" comes from the unique effect it has on its host's roots: as the parasite grows, it causes the host root to grow around it, forming a convoluted, woody growth resembling a carved rose. The plant itself consists of a dense, subterranean inflorescence (flower head) that pushes to the surface to flower. The flowers are small, reddish-brown, and emit a strong, musky scent to attract its primary pollinator: the short-tailed bat ( Chalinolobus tuberculatus ).

Plant Habitat

Natural Occurrence and Ecology

Dactylanthus taylorii is found in native lowland and montane forests, typically in areas with high rainfall and humidity. It parasitizes the roots of various native broadleaf trees, often growing on well-drained slopes. Its subterranean existence means its habitat is largely defined by the root systems of its host plants and the overall health of the forest ecosystem.

Growing Requirements

Soil Requirements

Prefers well-draining soil rich in organic matter.

  • Well-drained
  • Loamy

Light Requirements

Grows best in partial to full sun.

  • Full Sun
  • Partial Shade

Water Requirements

Requires regular watering during dry periods.

  • Regular
  • Drought tolerant once established

Planting and Establishing

Establishment Guidance

Plant Dactylanthus taylorii in a hole twice the width of the root ball.

Proper establishment is key to long-term success. Ensure the planting hole is twice as wide as the root ball and backfill with a mix of native soil and organic compost. Initial watering should be thorough, followed by regular monitoring during the first two growing seasons to ensure the plant becomes well-anchored and resilient to local climate fluctuations.

Landscaping Uses

Adds texture and form to modern landscapes.

In a landscape setting, this plant provides excellent structure and year-round interest. Its unique form and foliage can be used to create focal points or as a cohesive element in a larger native planting scheme. It pairs well with other New Zealand natives, allowing for the creation of diverse and resilient garden environments that reflect the natural beauty of Aotearoa.

Seasonal Care Calendar

Spring

Mulch and apply balanced fertilizer.

  • Fertilize
  • Mulch

Summer

Water deeply during dry spells.

  • Water
  • Check for pests

Autumn

Tidy up any dead foliage.

  • Prune lightly
  • Plant new specimens

Winter

Protect from heavy frosts if necessary.

  • Frost protection

When to Prune and How Much

Minimal pruning required to maintain shape.

  • Remove dead branches

Always use clean, sharp tools.

Regular maintenance through careful pruning ensures the plant remains healthy and maintains its desired shape. Focus on removing dead or diseased wood to promote better air circulation and prevent the spread of pathogens. 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 Pua O Te Rēinga

Cultivating Dactylanthus taylorii ( Dactylanthus taylorii ) 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 Dactylanthus taylorii 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 Dactylanthus taylorii , 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

Dactylanthus taylorii holds profound cultural significance for Māori, who know it as Pua o te Rēinga, the "Flower of the Underworld" or "Perfume of the Underworld." Its subterranean existence and strong musky scent evoke connections to the spiritual realm and the transition between life and death. The distinctive "Wood Rose" formed on host roots is also highly valued. Its rarity and unique biology make it a taonga (treasure) and a symbol of New Zealand's extraordinary and vulnerable indigenous flora.

  • 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

Dactylanthus taylorii is classified as "Nationally Vulnerable" under the New Zealand Threat Classification System. Its rarity is primarily due to habitat loss (deforestation), degradation of forest ecosystems, and predation by introduced pests. Introduced mammals like possums, rats, and pigs consume its fleshy flowers and "wood roses," severely impacting its reproduction and survival. Conservation efforts focus on predator control, habitat protection, and propagation initiatives.
