Metrosideros kermadecensis is a hardy, stout trunked shrub or small tree that is a dense bun shape when young, aging to a medium domed tree with a conical crown.
Dark green leaves with silvery undersides appear in opposites along the stems and spectacular crimson stamened pincushion or pom-pom type flowers adorn the plant through spring and summer.
