Description Best known as the world’s largest conifer, Coastal Redwood achieves its prodigious size along a 450-mile strip of land along the Pacific Coast beginning in Monterey California and extending north to southern Oregon.

This Northwest native conifer can attain an eventual height of over 200’ and a width of 40’. While young trees have a pyramidal shape, mature trees take on a narrow columnar form. In natural stands in northern California, the trees develop tall straight trunks with branches only in the upper canopy.

Leaves are mostly needle-like, flat, 2-ranked, 1” long and sharp pointed. The upper surface of the needles are dark green, while beneath there are 2 broad white stomatal bands running length-wise. Cones are egg-shaped, 1” long and brownish in color.

Bark is rich, red-brown and fibrous. The lumber of Coastal Redwood is of economic importance because of its high resistance to decay.

Coastal Redwood does best in full sun. It prefers moist, acid, deep and well-drained soils. In its prime growing region it thrives where winter rains and summer fog provide an even temperature and a high level of year-round moisture. Outside of the fog belt the trees don’t attain their size. Redwood is tolerant of flooding, making best growth along stream banks and flood plains
