How to Grow Houpara
Cultivating Pseudopanax lessonii ( Pseudopanax lessonii ) 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 Pseudopanax lessonii 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 Pseudopanax lessonii , 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
Houpara's bold, glossy foliage and coastal resilience make it a staple of northern native gardens and shelter belts, expressing a regional coastal aesthetic. Pseudopanax lessonii , also known by its Māori name Houpara, holds cultural significance primarily through its traditional uses by Māori and early European settlers in New Zealand. For Māori, the plant had several practical applications: the wood of Pseudopanax species, includingP. lessonii(referred to as "parapara"), was utilized as rollers for hauling canoes. Young tree stems were sharpened and fire-hardened to create lances for hunting kererū ōī (New Zealand pigeons). Māori crafted tokotoko, or walking sticks, by shaping living saplings. Early Pākehā settlers also found uses for the plant: the strong midribs of young leaves were repurposed as bootlaces and for repairing bridles and harnesses. The flexible trunks were used to make stock and horsewhips.

- 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
Pseudopanax lessonii , commonly known as houpara or coastal five-finger, is a New Zealand native tree. It is endemic to New Zealand, found in coastal forests and scrub from the Three Kings Islands to Poverty Bay and northern Taranaki. According to recent assessments in 2022-2023 using the New Zealand Threat Classification System (NZTCS), the current conservation status of Pseudopanax lessonii is "Not Threatened." While not currently endangered, populations can be threatened by browsing from possums, deer, and goats. It's important to note that in some areas, particularly outside its native distribution, houpara and its hybrids have escaped cultivation and can become invasive weeds, posing a threat to local biodiversity and even its own genetic background through hybridization with other Pseudopanax species.
