Rimu is the name of several species of tall New Zealand trees. One species is also known as red pine. The red pine’s timber, beautifully marked and much prized, is used in house building. Rimus may be planted to control soil erosion. They are majestic, tall trees with pale-green drooping branches and fine leaves pressed close along the stem. Like all pines, they have inconspicuous flowers that are either male or female. The flowers are borne on the ends of the branches, the males in catkins, the females in small cones. Each tree bears only male or female flowers.
