Thank you to “ginger749” on the UBC Botanical Garden Forums for submitting this photograph from Gold Coast, Australia. You can see the original, larger image in this thread. Many thanks – nice to see some late spring flowers from the southern hemisphere!
The story of the species Metrosideros excelsa or Pōhutukawa is doubly sad. Once fairly widespread in coastal areas of the North Island of New Zealand, the population of plants is in decline. This is due in part to a voracious alien, the Australian brushtail possum. Exhaustive details about this and other threats to the native New Zealand Metrosideros species are available from Project Crimson.
Despite its decline in New Zealand, the plant is flourishing in South Africa – so much so that it is now considered an invasive alien; Our Native Plant Invaders from the Royal New Zealand Institute of Horticulture has more on this threat to the fynbos.
The University of Melbourne’s Horticulture program had a “Plant of the Month” feature (it seems to be defunct) – it once featured Metrosideros excelsa.
