Chilean firetree, Chilean firebush, Notro or Ciruelillo in Spanish (Embothrium coccineum), is a small evergreen tree in the family Proteaceae. It grows in the temperate forests of Chile and Argentina.
It grows 4–15 m (13–50 ft) tall and can reach 50 cm (20 in) in diameter. The bark is dark grey with light spots. Its wood is light pink in color, and being very soft but durable, is used for spoons, kitchen vessels and another craft articles.
"Perhaps no tree cultivated in the open air in the British Isles gives so striking and brilliant a display as this does."
It is pollinated by both hummingbirds and insects in its natural range.
In 2013, researchers reported their findings that E. coccineum has the unique ability to access normally inaccessible forms of various nutrients, especially phosphorus. It does this by creating a dense root mass called cluster roots when in its seedling stage. These cluster roots exude acidic substances which are able to transmute the otherwise inaccessible forms of nutrients into forms that are biologically useful. These nutrients are then made available to other plants from the leaf litter of E. coccineum, making it a valuable keystone plant in certain terrains.
