Common names include coast redwood, coastal redwood and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–1,800 years or more. This species includes the tallest living trees on Earth, reaching up to 379 feet (115.5 m) in height (without the roots) and up to 29.2 feet (8.9 m) in diameter at breast height (dbh). These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres (8,500 km2) along much of coastal California (excluding southern California where rainfall is not suf |

The sprouts from the burls have been used in making baskets;
The plant develops a thick covering of a soft and fibrous bark (you can punch it hard without hurting your hand). This can be harvested without harm to the tree and used as an insulating or stuffing material; A fine bark dust that is produced whilst doing this is a good soil conditioner; This fibrous bark is also used for making paper. Branches can be harvested at any time of the year from logged trees, the bark is cut into useable pieces and soaked in clear water prior to cooking for 6 or more hours with lye. The fibres are beaten for six hours in a ball mill and the paper is a brown colour;
Wood - straight-grained, knot-free, light, soft, not strong, very durable in contact with the soil. A high quality and easily worked lumber, it is used for joinery, fence posts, construction etc; | | Vegetative Spread Rate [2] | None | | | Flower Color [2] | Yellow | | Foliage Color [2] | Green | | Fruit Color [2] | Brown | | | Fruit Conspicuous [2] | Yes | | | Height [3] | 361 feet (110 m) | | Width [3] | 66 feet (20 m) | | | Hardiness Zone Minimum [1] | USDA Zone: 7 Low Temperature: 0 F° (-17.8 C°) → 10 F° (-12.2 C°) | | Hardiness Zone Maximum [1] | USDA Zone: 10 Low Temperature: 30 F° (-1.1 C°) → 40 F° (4.4 C°) | | Light Preference [2] | Mostly Shady | | Soil Acidity [2] | Moderate Acid | | Soil Fertility [2] | Infertile | | Water Use [1] | High |
