New Zealand Broadleaf Griselinia littoralis
ABOUT
Griselinia littoralis, commonly known as New Zealand broadleaf or Kapuka, is an evergreen shrub with a dense, bushy habit. Its standout feature is the glossy, apple green leaves that are broadly oval in shape, with a leathery texture. The edges of the leaves are often slightly wavy and the foliage provides a lush, tropical feel. Small, inconspicuous yellow-green flowers may appear in spring, followed by purple or blackish berries that are favored by birds. The berries are only produced by female plants if a male pollinator is nearby. The bark of New Zealand broadleaf is light gray and can become attractively mottled as it ages. This plant is popular for creating hedges and screens due to its full, compact appearance and attractive foliage.

- Water
For the New Zealand Broadleaf or Griselinia littoralis, water should be applied deeply and thoroughly to ensure the soil is moist. In general, watering once a week is sufficient, but this can vary based on climate conditions. During hot and dry periods, more frequent watering may be necessary, potentially twice a week. Ensure each time that the plant receives 1 to 2 gallons per watering, depending on the size of the plant and the soil's ability to retain moisture.
- Light
New Zealand Broadleaf thrives best in full sun to partial shade. An ideal spot is one where the plant can receive at least 4 to 6 hours of sunlight daily, though it can also tolerate some light dappled shade. Avoid placing it in deeply shaded areas as this can impede its growth.
- Temperature
Griselinia littoralis, or New Zealand Broadleaf, is hardy and can tolerate a range of temperatures, yet it prefers a moderate climate. The ideal temperature range for this plant is between 50°F and 70°F. It can survive minimum temperatures down to 20°F but cannot withstand prolonged periods of extreme cold or sudden frosts.
- Pruning
Prune New Zealand Broadleaf to maintain shape and promote healthier, denser growth. It's best to prune in late winter or early spring before new growth begins. Depending on the desired size and shape, pruning can be done annually or as needed when the plant becomes too large or unruly.
- Cleaning
As needed
- Soil
Griselinia littoralis, commonly known as New Zealand broadleaf, thrives best in well-draining soil with a mix of compost, loam, and sand, promoting good root growth. The ideal pH range for this soil mix should be slightly acidic to neutral, about 5.5 to 7.0.
- Repotting
New Zealand broadleaf should be repotted every 2-3 years to ensure it has enough space to grow and to refresh the soil, as older soil can become compacted and nutrient-depleted over time.
- Humidity & Misting
New Zealand broadleaf prefers moderate humidity levels, but as a hardy plant, it can tolerate a range of conditions, provided it isn't in an excessively dry environment for prolonged periods.
- Suitable locations
Indoor
Place New Zealand broadleaf in bright, indirect light, away from drafts.
Outdoor
Plant in well-drained soil, shelter from strong winds, in partial shade or sun.
Hardiness zone
7-9 USDA
- Life cycle
Griselinia littoralis, commonly known as New Zealand Broadleaf or Kapuka, begins its life cycle as a seed, which, when conditions are favorable, germinates in the soil. After germination, a seedling emerges and establishes its first true leaves, entering the juvenile phase. As the plant develops, it progresses into the vegetative stage, characterized by significant growth of stems, leaves, and root systems. Upon reaching maturity, the Kapuka produces small yellow-greenish flowers, generally in spring, signifying the reproductive phase where it intends to produce seeds. Following pollination, which is primarily aided by the wind, the plant develops small purple fruits that contain seeds, thus completing the life cycle when these seeds are dispersed into the environment. The New Zealand Broadleaf is known for its hardiness and evergreen nature, so it continues to grow and can live for many years unless affected by environmental factors or disease.
- Propogation
Propogation time
Spring-Early Summer
The most popular way to propagate Griselinia littoralis, commonly known as broadleaf or New Zealand broadleaf, is through semi-hardwood cuttings. The ideal time to take these cuttings is in late summer. A semi-hardwood cutting is made from the current year's growth that has started to harden or mature. Cuttings should be about 4 to 6 inches (10 to 15 centimeters) long, and the lower leaves should be removed. The cut end of the cutting can be dipped into rooting hormone to encourage root growth. The prepared cutting should then be placed in a pot filled with a mix of peat and perlite or a similar free-draining propagation medium. It's essential to maintain a humid environment around the cutting, typically achieved by placing a plastic bag or a propagator over the pot to retain moisture. Cuttings generally root within 6 to 8 weeks, after which they can gradually be exposed to normal conditions before being potted on.
