Metrosideros thomasii is an exotic tree / shrub, originally from New Zealand.
There he can grow up to 3 to 5 meters high and more than 20 years old. Is also known under the name ironwood tree.
The bloom is amazing, fire-red (crimson) flowers adorn the bush from the end of spring until the summer. Plant is evergreen in winter. The leaves are gray / green in color. As a young plant it is a shrub, but as they grow older they grow on a short trunk and then branch in an umbrella shape.

The plant may be given liquid fertilizer during flowering, once a week is sufficient. Keeping slightly moist is sufficient, even older plants are fairly drought tolerant for once. A sunny warm place is ideal for the Metrosideros thomasii. The ironwood tree also tolerates pruning well, this is best done after flowering and so you keep the plant in the desired shape and height.

After flowering, restrained with fertilization, once a month a small amount is sufficient. Do not administer fertilizer in the winter.
