This genus of plants has about thirty species of evergreen trees and shrubs, originating in the islands of Hawaii, Australia and New Zealand. They have an erect, enlarged bearing, with very dense and branched foliage; the leaves are oval, dark green in color, covered with a thick whitish-gray hair. From April until the end of summer, terminal inflorescences produce bright, red, pink, orange or yellow flowers, with a feathery appearance, very particular; the flower buds are covered with a slight whitish hair. In nature these plants can reach majestic dimensions, close to 15-20 meters, grown in our gardens they remain more modest in size, 1.5-2 meters, developing quite slowly.
THE Metrosideros they are plants which, naturally, can reach considerable heights, but which, when grown, do not exceed 2 meters, thus also being able to be planted in pots.
The best exposure for these shrubs is in a sunny place, or in partial shade, guaranteeing them at least a few hours of sunshine.
These plants fear the intense cold, even if some species can bear temperatures of some degrees below zero, it is good to plant them in a place sheltered from the cold, for example near a wall of the house; in areas where winters are very harsh the plant must be covered with non-woven fabric, or, if grown in pots, hospitalized in a cold greenhouse.
