About
Metrosideros fulgens (scarlet rātā, rātā vine or in Māori akatawhiwhi) is a forest liana or vine endemic to New Zealand. It occurs in coastal and lowland forest throughout the North Island, on the west coast of the South Island and on the Three Kings Islands north of Cape Reinga. It is one of a number of New Zealand Metrosideros species which live out their lives as vines, unlike the northern rātā (M. robusta), which generally begins as a hemi-epiphyte and grows into a huge tree. Scarlet rātā is one of the better-known species of rātā vines, because it flowers in autumn or winter, and is often highly visible on well-lit host trees along forest roads, with vibrant displays of large red flowers (sometimes orange or yellow) that rise above the forest canopy.
How to grow it
There are several cultivars of M. fulgens available, mostly selected for their flower colours.
Metrosideros fulgens ‘Gold’/'Aurata' has bright yellow flowers from late summer to early winter and grows to 1.5 by 1.5 metres, taking several years to reach this size. It has attractive fresh light green foliage, and can be trimmed to form an informal hedge. M. Aurata was first encountered in 1890 near Collingwood by a Mrs S. Featon of Gisborne, and was first thought to be a separate species (Metrosideros aurata). M. Gold was the name used when introduced into cultivation, and was sourced in the same area and time as M. Jaffa below.
