Metrosideros is a genus of approximately 60 trees, shrubs and vines mostly found in the Pacific region. Most of the tree forms are small, but some are exceptionally
large, the New Zealand species in particular. . Perhaps the best-known species are the pohutukawa (Metrosideros excelsa) of New Zealand. Metrosideros seeds can be dispersed by the wind, which probably
accounts for their wide distribution. They are often found as pioneer
trees on lava flows and on mountain ridges.
The pohutukawa of New Zealand has several cultivars grown in Australia, Hawai and Califorinia and it has been planted successfully in the north of Spain and Portugal.These ones are from the Foz Gardens in Porto, Portugal.
