Plant Description

Identification and Physical Characteristics

Fuchsia excorticata , commonly known as Tree Fuchsia or K tukutuku, is the largest species of Fuchsia in the world and is endemic to New Zealand Discover more about native grasses. This broadleaf semi-evergreen perennial can grow as a shrub or a tree, typically reaching heights of 8-12 meters, but can grow up to 15 meters in ideal conditions. A distinguishing feature is its bark, which is light brown/orange, extremely thin, and peels in papery strips. The leaves are generally dark green on the upper side and paler, often silvery, on the underside, with serrated margins. They can sometimes be tinged with red or purple. Unlike most New Zealand native trees, it is deciduous in cooler southern regions, though it may be evergreen in warmer areas. Its flowers are solitary and pendulous, emerging in spring and summer, starting green, then transitioning to violet, pink, or dark purple. These nectar-rich flowers attract birds like tūī, bellbirds, and hummingbirds. Following the flowers, the tree produces small, dark purple berries known as k nini by Māori, which are edible and have a sweet, juicy taste.

How to Grow Tree Fuchsia

Cultivating Fuchsia excorticata ( Fuchsia excorticata ) 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 Fuchsia Excorticata 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 Fuchsia excorticata , 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

Fuchsia excorticata , known as k tukutuku by the Māori people, holds significant cultural importance in New Zealand. It is the world's largest fuchsia species and is unique among New Zealand's native trees for being deciduous and shedding its bark in papery strips.Food Source:The dark purple berries, called k nini, were a vital traditional food source for Māori and were also enjoyed by early European settlers, who used them to make jams and puddings.Medicinal Practices (Rongoā Māori):K tukutuku was used in traditional Māori medicine. Its leaves were an ingredient in vapor baths to assist with childbirth and were also used to treat fevers and bruises.Dyes and Cosmetics:The berries were traditionally used to create a purple dye. The distinctive blue pollen from its flowers was used by Māori women as a form of lipstick or makeup.Seasonal Indicator:The blooming of k tukutuku flowers in September served as a traditional indicator in the maramataka (Māori lunar calendar) in the North Island, signaling the time to plant early spring crops like kūmara.Symbolism:K tukutuku symbolizes resilience, beauty in adversity, enduring strength, and grace under pressure, partly because of its ability to thrive in challenging environments. Its peeling bark is seen to represent protection and renewal. It also embodies grace and mana, and is associated with self-discovery and valuing contributions.Ceremonial Use:Due to its striking appearance and rich cultural significance, k tukutuku is often incorporated into formal and traditional events in New Zealand, such as anniversaries and cultural festivals, to celebrate resilience and unity.Ecological Role:Beyond its human uses, k tukutuku plays a crucial role in supporting native wildlife by providing nectar and berries for birds like tūī, bellbirds, and kererū, which are important for seed dispersal.

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

Fuchsia excorticata , also known as tree fuchsia or k tukutuku, is classified as "Not Threatened" under the New Zealand Threat Classification System (NZ TCS). This status has been consistent in assessments from 2004, 2009, 2012, 2017, and 2023.While generally not threatened, the species faces regional declines in some areas, such as Auckland. A significant threat to Fuchsia excorticata is the common brushtail possum, an introduced species in New Zealand, which heavily browses the tree, often leading to defoliation and death. Other threats include plant competitors and, to a lesser extent, goats.
