Plant Description

Identification and Physical Characteristics

Gaultheria macrostigma , also known as Large Stigma Snowberry or Prostrate Snowberry, is an evergreen shrub endemic to New Zealand. It is a low-growing, sometimes prostrate, tangled shrub that can reach up to 0.5 meters in height and 1 meter in spread. Its stems are wiry, flexuous, often interlaced, and can have bristle-like hairs on the twigs. The leaves are narrow, leathery, dark green or brownish, 6-15mm long by 1-3mm wide, with several prominent teeth on the margins, and are present all year. Small, white or pinkish, bell-shaped flowers are clustered at the tip of the twigs, appearing from April to May. The fruit is a globose berry, about 6mm in diameter, which can be white to red and lobed. This species is hardy to UK zone 8 and prefers mildly acid to very acid, well-drained soils. It is found in montane to lower sub-alpine open grassland and rocky places in New Zealand.

How to Grow Gaultheria Macrostigma

Cultivating Gaultheria macrostigma ( G. macrostigma ) 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 Gaultheria macrostigma 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 Gaultheria macrostigma , 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

Gaultheria macrostigma , also known as Large Stigma Snowberry or prostrate snowberry, holds cultural significance, particularly in New Zealand.In Māori tradition, various Gaultheria species, including Gaultheria macrostigma , are culturally valued and known by names such as tāwiniwini, kāma, and niniwa. This plant is also recognized for its ecological services in New Zealand, contributing to the diversity of heath family plants in upland environments and being valued in restoration efforts and gardens.Beyond its ecological role, Gaultheria macrostigma has traditional uses. It is employed in traditional medicine for its antiseptic and anti-inflammatory properties. The fruit of Gaultheria macrostigma is edible and can be consumed raw or cooked. Other Gaultheria species also have traditional medicinal and edible uses; for instance, Gaultheria procumbens is a traditional source of wintergreen flavoring, and its leaves are used for tea.

  • 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

Gaultheria macrostigma , also known as Large Stigma Snowberry or prostrate snowberry, is a plant species endemic to New Zealand. Its conservation status is currently classified as "Not Threatened" by the New Zealand Threat Classification System (NZTCS), a status it has held since at least 2004. This low-growing shrub is found in upland and montane regions throughout New Zealand.
