Plant Description
Botanical Features
P«riri (Vitex lucens) is an evergreen tree endemic to New Zealand. It can grow up to 20 meters tall, with some specimens reaching 29 meters, and features a broad, spreading crown and a trunk that can be up to 1.5 meters in diameter. The bark is typically smooth and light brown, though it can also be flaky or thick and corky with deep ridges. The leaves of the p«riri are glossy, dark green, leathery, and palmate, usually composed of five (sometimes three) leaflets, with the two lowest leaflets being smaller. These leaves also contain small pockets called domatia where veins meet. P«riri produces large, tubular flowers that resemble snapdragons, ranging in color from fluorescent pink to dark red, rose pink (most common), or occasionally white with a yellow or pink blush. These flowers are rich in nectar and attract native birds, often blooming year-round, with the heaviest flowering occurring in winter. Following the flowers, the tree bears bright red (or rarely pale yellow) drupes, which are cherry-like fruits. While astringent and not particularly nutritious for humans, these fruits are a vital food source for native birds.

How to Grow P«riri
P«riri is a magnificent native tree that, while slow-growing, is relatively easy to establish and cultivate given the right conditions. Its impressive size, beautiful flowers, and ecological significance make it a highly rewarding tree to grow. It thrives in warm, frost-free environments with ample sunlight and well-drained, fertile soil. Young trees require protection from frost and strong winds, but once established, P«riri is a robust and long-lived specimen.
From Seed
P«riri can be readily grown from seed, although germination can be a slow process. To improve and hasten germination, it is recommended to scarify the hard seed coat. This can be done by lightly sanding or nicking the seed. After scarification, soak the seeds in cold water for 48 hours, changing the water daily. Sow the treated seeds in a well-draining seed-raising mix, lightly covering them. Maintain consistent moisture and warmth. Germination can still take several months, so patience is key. Once seedlings are large enough to handle, pot them into individual containers and grow them on in a sheltered, frost-free location for their first few years.
From Cuttings
P«riri can also be propagated from semi-hardwood cuttings, typically taken in late summer or autumn. Select healthy, vigorous shoots that are about 6-8 inches long. Remove the lower leaves and, if desired, dip the cut end in a rooting hormone to encourage root development. Plant the cuttings in a well-draining medium, such as a mix of perlite and peat, and ensure high humidity around the cuttings, perhaps by covering them with a plastic bag or placing them in a propagator. Keep the medium consistently moist but not waterlogged. Rooting can be slow and success rates can vary, but this method allows for the propagation of genetically identical plants to the parent.
Pests & Diseases
The P«riri Moth
The main "pest" of the p«riri is the larva of the p«riri moth (Aenetus virescens), which bores into the trunk, creating characteristic holes. This is a natural process and does not usually harm a healthy, established tree.
Cultural Significance
Vitex lucens, commonly known as Pūriri, holds profound cultural importance, particularly within Māori culture in New Zealand. The common name "Pūriri" itself is the traditional Māori name for the tree.
Māori Cultural Significance and Traditional Uses:
- Sacred and Spiritual Associations: To many Māori tribes, the Pūriri tree was deeply sacred and associated with mourning and the burial of the dead. In some traditions, after the death of a chief or person of high mana, the body would be adorned with a coronet of pūriri leaves and washed with an infusion of the leaves and water. After decomposition, a ritual scraping ceremony was performed, and the bones were entombed in the hollow of a Pūriri tree. The ancient burial tree Taketakerau in Ōpōtiki, estimated to be around 2000 years old, served as an important burial site and was considered highly sacred. Despite these associations with death, Bay of Islands Māori also considered Pūriri a symbol of joy, using the proverb "Ka kata ngā pūriri ō taiamai" (the pūriri trees of the Bay of Islands are laughing with joy) as a greeting or to honor guests.
- Traditional Uses: Māori extensively used Pūriri in pre-European times. The durable and rugged wood was prized for carving, making weapons, implements, and for constructing defensive forts and palisades. It was reputedly so dense that shotgun shells would ricochet off it. The wood was also used for furniture and buildings.
- Medicinal Applications: Infusions of Pūriri leaves were used by Māori for medicinal purposes, including bathing sprains, backaches, and ulcers, or drunk for sore throats. One of the chemical constituents of the leaves, the methyl ester of p-hydroxybenzoic acid, has even been patented as a germicide.
- Other Practical Uses: The tree produces a red dye that Māori used for tattooing and dyeing. Its resistance to rot made its wood useful for fence posts and other outdoor construction projects. It was also the preferred material for constructing eel traps because it was one of the only native timbers that would sink.
Beyond its cultural significance, Pūriri also plays an important ecological role as a food source for native birds like tūī and kererū, and provides habitat for various native insects and animals.
Bonus Tip
Pūriri (Vitex lucens) is not only a magnificent tree but also holds several fascinating distinctions. It is one of New Zealand's largest native flowering trees, with some specimens estimated to be up to 1,700 years old, making them ancient living monuments. Its vibrant pink, nectar-filled flowers bloom almost year-round, peaking in winter, providing a crucial food source for native birds like tūī and bellbirds when other nectar sources are scarce. Uniquely, the flowers have evolved to be bird-pollinated, featuring a tube shape and abundant nectar, with hairs at the base to prevent insects from stealing the nectar. The tree's exceptionally dense and durable timber, once referred to by early European settlers as "ironwood," was so hard that shotgun shells were reputed to ricochet off it, highlighting its incredible resilience.
