The Coast redwood or Californian redwood can reach 115 m (377 ft) tall with a trunk diameter of 9 m (30 ft). It has a conical crown, with horizontal to slightly drooping branches. The bark can be very thick, up to 1-foot (30 cm), and quite soft and fibrous, with a bright red-brown color when freshly exposed (hence the name redwood), weathering darker. Flattened needles turning brown in winter. The root system is composed of shallow, wide-spreading lateral roots.
