How to Grow Scarlet Rata
Cultivating Metrosideros fulgens ( Metrosideros fulgens ) 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 Metrosideros fulgens 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 Metrosideros fulgens , 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
Metrosideros fulgens , also known as climbing rātā, holds significant cultural importance, particularly for the Māori people of New Zealand. The Māori have several names for the plant and its flowers, with 'aka' and 'puatawhiwhi' being commonly used for the plant and flower respectively. Europeans often refer to it simply as 'climbing rata'.Tools and Construction:The vine was used as a flywheel on cord drills by Ngāti Porou and for binding adze handles. Along with kareao, it was extensively used for tying fences, platforms, and the heavy framework of houses.Medicinal Uses:Various parts of the plant were utilized for their medicinal properties. The juice was used as a cough mixture. Sap was applied for watery, inflamed eyes by the T «hoe people. The inner bark from the eastern side of the tree was used to heal sores and stop bleeding. Bark boiled with rimu and kauri created a lotion for sore backs of horses, and bark steeped in water was used for ringworm. Sap from short lengths of vine was also blown on wounds.Refreshment:Bushmen would quench their thirst with the vine's juice, which was described as having a clear, bright pinkish hue and tasting somewhat like dry cider. The astringent juice was also consumed as a beverage.Beyond its direct uses, Metrosideros fulgens is appreciated for its vibrant appearance, with bright orange to scarlet flowers that bloom from autumn to early spring, bringing colour to the forest during winter. These nectar-rich flowers also provide an important food source for native birds and insects, and historically, native bats and lizards, contributing to the ecosystem's health.

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
Metrosideros fulgens , commonly known as scarlet rata vine, climbing rata, or akatea, is a forest liana or vine native to New Zealand. As of 2017-2018, Metrosideros fulgens is classified as "Threatened - Nationally Vulnerable" in New Zealand. This marks a decline from its previous "Not Threatened" status in assessments conducted in 2004, 2009, and 2012. The most significant threat to Metrosideros fulgens , along with other native myrtle species in New Zealand, is myrtle rust (Austropuccinia psidii), an invasive fungal disease that was first identified in New Zealand in May 2017. Currently, there is no effective method for controlling myrtle rust in wild populations, with fungicide application only being a last resort in very limited areas. Myrtle rust has been observed infecting Metrosideros fulgens both in natural environments and through experimental inoculation, demonstrating high levels of infection. Ongoing research is focused on understanding the susceptibility of various Metrosideros vine species to myrtle rust to inform future conservation strategies.
