Meryta sinclairii (Pukanui, Puka)


Michael's Opinion

This specimen is a small hardy evergreen tree, endemic to New Zealand but cultivated in other parts of the country. Glossy, beautiful large leaved tree used for urban landscaping due to its wind and salt tolerance. Ideal for warm climates as a specimen tree because of the pleasant form, the bird attracting fruits, and the minimal pruning required.

It was then found by William Mair who succeeded in fruit and leaf production and forwarded the specimen to Dr. Joseph Hooker at Kew.

Description and Growing Information

General DescriptionA small evergreen tree native to the North Islands of New Zealand. A tropical/subtropical looking tree that is adaptable to warmer climates. Has a rounded crown which requires little to no pruning.
ID CharacteristicLarge leathery leaved tree. Bunches of black ripe fruit. Wind and salt tolerant, great for urban planting in warmer climates.
ShapeUpright with a rounded crown. As a young specimen it grows single trunked then branches out after first inflorescence.
LandscapeUsed as a specimen tree, borders, urban planting, and coastal gardens. A common street tree in New Zealand and can be found in California and Florida.
PropagationPropagation mainly happens by fresh seeds, that are known to be big and fleshy, therefore it must be soaked in water for a day or two to remove all the fruit off the seed. Best to be sown as soon as it is ripe in a seed raising mix placing only a pinky finger’s width beneath the soils surface. Keep the soil moist, not letting it dry out until true leaves form. After the true leaves pop up it can be transferred to pot in a high nutrients potting mix. Seeds also germinate beneath parent plant, or they may self-seed. Can be grown from softwood tip cuttings but is less successful because the stems are chunky and may die before a root strike. If there is a root strike it may not be supported because of its large leaves.
CultivationWind and salt tolerant, becoming drought tolerant once established. Prefers full to partial sun with loamy, moist, well-draining soil.
PestsNo known pests besides rodents damaging young plants. May also be susceptible to phytophthora or verticillium wilt.
