Evergreen climber which climbs by adhering to tree trunks and other surfaces with its adventurous roots.
Prefers warm moist habitats and grows up to 15m long or more. Produces a mass of carmine coloured flowers in spring.
Prefers a position in well-draining soil. If you intend to use Metrosideros carminea as a climber, then find a spot in the shade, preferably where it can grow towards the light. If you want to grow it as a shrub, then a sunny position is best.
