Pterophylla racemosa, commonly known as kāmahi, is an evergreen tree endemic to the forests of New Zealand, ranging from lowland to montane regions. It can reach up to 82 feet (25 meters) in height and is characterized by its dark green, leathery leaves. From spring to summer (October to March in the Southern Hemisphere), kāmahi produces abundant clusters of creamy white flowers that are a valuable nectar source for native birds and insects. The tree’s ecological role extends to providing habitat and food for a variety of wildlife, and it has been traditionally used by Māori for dyeing and medicinal purposes.

Kāmahi is valued for its resilience and adaptability, thriving in a wide range of climates and soil types, from wet to moderately dry conditions. It prefers well-drained soils and can tolerate partial shade, although it flourishes in full sunlight. In cultivation, it is often used for reforestation projects, as a specimen tree in large gardens, and for its ecological benefits in supporting native biodiversity. Gardeners should note that kāmahi can be susceptible to root rot in poorly drained soils and may require protection from strong winds due to its shallow root system.CC BY-SA 4.0
