Coast Redwood
Sequoia sempervirens
  
About Coast Redwood (Sequoia sempervirens) 25 Nurseries Carry This Plant Sequoia sempervirens is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae). It is an evergreen, long-lived, monoecious tree living for up to 2,200 years, and this species includes the tallest trees on Earth, reaching up to 115.5 meter (379.1 feet) in height and 8 meter (26 feet) diameter at breast height. It is native to coastal California and the southwestern corner of Oregon within the United States. This region is characterized by wet winters and cool, foggy summers. Fog drip is important to the total water budget for this tree. The name sequoia is sometimes used as a general term for the subfamily Sequoioideae in which this genus is classified, together with Sequoiadendron (Giant Sequoia) and Metasequoia (Dawn ); as a common name, it usually refers to Sequoiadendron.

These are beautiful trees and easy to grow in their native range but may quickly become too large for many residential gardens. Provide plenty of room and adequate moisture throughout the year. Outside its native range it may show signs of stress and its lifespan may be shortened. The tree is sensitive to water quality and air quality issues as well as low humidity and drying winds.

Here's a great video about this plant from the Jepson Herbarium at UC Berkeley...
