Pōhutukawa

Metrosideros excelsa

Also known as New Zealand Christmas Tree, Iron Tree

Vibrant crimson blossoms dominated by brush-like stamens erupt across coastal bluffs every December, giving this resilient tree its widespread association with southern hemisphere midsummer. Aerial roots dangle from sprawling, contorted boughs, helping anchor mature specimens into sheer rock faces blasted by ocean salt spray. In Māori tradition, an ancient pōhutukawa clinging to the cliff edge at Cape Reinga marks the sacred leaping-off place where departing spirits begin their journey back to the ancestral homeland of Hawaiki.

Support conservation
Avoid picking flowers or trampling exposed root shelves on fragile coastal cliff edges.
Responsible observation
  • Flowering Season: Look for peak crimson stamen displays between late November and mid-January.
  • Coastal Scouting: Check seaside bluffs and coastal reserves to view sprawling multi-trunk boughs supporting aerial roots.
  • Biosecurity Care: Clean footwear and gear before entering native bush to avoid spreading fungal pathogens like myrtle rust.
