1624045 firetree Morella faya Native to the Canary Islands, Madeira, and the Azores. It was introduced to Hawaii as an ornamental, probably by Portuguese laborers, who made wine from the fruit. It was first recorded in Hawaii in 1900. Firetree increases available nitrogen on new volcanoe sites. This allows nonnative plants to invade before native species have a chance to become established.
