Identification and Physical Characteristics

Narrow-leaved Māhoe ( Melicytus lanceolatus ) is a slender, erect, small tree endemic to New Zealand, growing up to 5-6 meters tall Discover more about native trees. Its bark is brownish-grey, brown to white, slightly wrinkled, and features prominent lenticels. Its vibrant green leaves are long, thin, and narrow (lanceolate in shape), typically measuring 5-16 cm long by 0.5-2 cm wide, with a finely serrated margin, sometimes curving downwards, giving them a willow-like appearance. The plant produces small, fragrant flowers, about 5 mm in diameter, which occur in clusters of two to six along bare branches or occasionally from leaf axils. These flowers can appear yellow, dark purple, or a combination of both. Following flowering, it produces dark purple, subglobose berries, 4-6 mm in diameter, containing 6-12 minutely tuberculate seeds. It prefers moist, cool areas with high rainfall, thriving in lowland to montane forests.

How to Grow Narrow-Leaved Māhoe

Cultivating Melicytus lanceolatus(Melicytus lanceolatus) 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 Melicytus Lanceolatus 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 Melicytus lanceolatus, 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

Melicytus lanceolatus, also known as narrow-leaved Māhoe or Māhoe-wao, holds cultural significance primarily within Māori traditions in New Zealand. Its cultural importance stems from its various traditional uses and recognition:Traditional Medicine (Rongoā Māori):The bark and leaves ofMelicytus lanceolatuswere utilized in traditional Māori medicine to address minor ailments.Timber Use:Its light and soft wood was employed for temporary construction and crafting implements, similar to how Whiteywood was used.Food Source:While not a primary food source, the small berries of the plant were occasionally consumed during travel.Environmental Indicator:The presence ofMelicytus lanceolatuswas recognized as an indicator of suitable growing conditions for other food plants.Cultural Recognition and Aesthetics:Traditional Māori knowledge holders distinguished this plant from Whiteywood due to its elegant form. It is valued for its graceful appearance and is often associated with forest margins and protected valleys.Indigenous Naming:One of its indigenous names, "Kaiwētā," translates to "wētā food." This name suggests an association with wētā (tree wētā) living in holes within the tree, giving the impression that the wētā consume the plant.

  • 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

Melicytus lanceolatus, commonly known as narrow-leaved Māhoe or Māhoe-wao, is a small tree endemic to New Zealand. Its current conservation status, as of 2023, is classified as "Not Threatened" under the New Zealand Threat Classification System (NZTCS). However, it is also categorized as "At Risk - Naturally Uncommon" due to habitat loss and its naturally restricted distribution. While not considered threatened overall,Melicytus lanceolatusfaces challenges from browsing by introduced mammalian species, such as red deer, fallow deer, white-tailed deer, and feral goats, which consume its foliage. Competition from invasive weeds and general habitat loss also pose ongoing issues. This species plays a vital ecological role in New Zealand's native forests, serving as a food source for native birds and supporting diverse communities of forest invertebrates. It is found across the North Island, South Island, and Stewart Island, typically in moist, cool areas with high rainfall, from sea level up to 915 meters. The plant is increasingly valued in native gardens and restoration projects due to its elegant form and moderate growth habit.
