Metrosideros–commonly known as New Zealand Christmas tree–is a subtropical tree or large shrub that bears colorful red flowers with many stamens from spring to early summer. Metrosideros is native to New Zealand.

Metrosideros can be grown as a specimen, hedge, or screen. It takes well to pruning and clipping. It can be planted on coastal sand dunes and cliffs; it tolerates salt spray and persistent wind once established. It is best grown in frost-free regions.

Metrosideros grows best with regular water; however, once established it will grow with just supplemental water.

Metrosideros is a genus of about 50 species of dwarf to tall, upright, evergreen shrubs and trees native to rainforests and river valleys from New Zealand to South Afric
