Cedrus
Also known as Cedar
Cedrus, with the common English name cedar, is a genus of coniferous trees in the plant family Pinaceae (subfamily Abietoideae). They are native to the mountains of the western Himalayas and the Mediterranean region at high altitudes. The trees grow tall with a cylindrical trunk and a wide leafy crown. The cones are erect; the leaves grow in tufts of 15–45 needle leaves, which can be bright green or blue-green with a waxy coat. When the cones are mature, they disintegrate to release the seeds, which are winged. Both pollen and seeds are wind-dispersed.
AI overview
Cedrus, commonly known as cedar, is a genus of tall coniferous trees native to high-altitude regions in the western Himalayas and Mediterranean areas, recognizable by their cylindrical trunks, wide crowns, and needle-like leaves that grow in distinctive tufts. These trees are ecologically significant because they reproduce and spread primarily through wind-dispersed pollen and seeds, allowing them to thrive across their mountainous native habitats.

Cedars are often planted as ornamental trees in parks and large gardens, while others are grown as bonsai. Cedar wood and cedarwood oil are naturally repellent to moths, and have an attractive, long-persistent scent.
