Plant Description
Identification and Physical Characteristics
Pennantia baylisiana , commonly known as the Three Kings Kaikomako, is a legendary tree reaching up to 8 metres in height Discover more aboutNew Zealand. It is famously known as one of the rarest trees in the world, with only a single wild specimen discovered in 1945. It forms a small, often multi-trunked tree with a broad, spreading crown. The foliage is particularly distinctive, featuring large, leathery, and highly glossy dark green leaves that can measure up to 16 cm long. These leaves often curl slightly at the margins, giving the canopy a textured appearance. The bark is a pale greyish-brown and is often covered in small raised spots called lenticels. In cultivation, it produces clusters of small white flowers, which eventually develop into fleshy purple-black fruits.

Plant Habitat
Natural Occurrence and Ecology
In the wild, the last remaining specimen of Pennantia baylisiana was found growing on a rocky scree slope on Great Island in the Three Kings group. This position likely protected it from the goats that once decimated the island's vegetation. The species is adapted to rocky, well-draining soils and is naturally resilient to the harsh, windy, and salt-laden environment of offshore islands. In cultivation, it performs best in fertile, free-draining soils rich in organic matter.

How to Grow Three Kings Kaikomako
Cultivating Pennantia baylisiana ( Pennantia baylisiana ) 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 Pennantia Baylisiana 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 Pennantia baylisiana , 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
The Three Kings Kaikomako holds immense cultural and symbolic value. For Māori, particularly the Ngāti Kurī iwi who are the kaitiaki (guardians) of the Three Kings Islands, the tree is part of their ancestral landscape. Its rescue from the very edge of extinction is a source of pride and a symbol of the resilience of the New Zealand flora. It serves as a powerful educational tool, reminding us of the impact of introduced species and the importance of proactive conservation management.Sacred to Ngāti Kurī as part of their ancestral home.A symbol of botanical resilience and scientific success.Educational icon for New Zealand conservation.

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
Pennantia baylisiana is one of New Zealand's most high-profile conservation stories. Classified as 'Threatened - Nationally Critical', it was once reduced to a single living individual. Intensive scientific efforts, including the use of hormones to induce self-pollination, have allowed for its successful propagation. Today, thousands of young trees have been grown and distributed to secure the species against extinction, though genetic diversity remains extremely low.
