Giant Sequoia (Sequoiadendron giganteum) - Description
Sequoiadendron giganteum (giant sequoia, giant redwood, Sierra redwood, Sierran redwood, or Wellingtonia) is the sole living species in the genus Sequoiadendron, and one of three species of coniferous trees known as redwoods, classified in the family Cupressaceae in the subfamily Sequoioideae, together with Sequoia sempervirens (coast redwood) and Metasequoia glyptostroboides (dawn redwood). The common use of the name "sequoia" generally refers to Sequoiadendron giganteum which occurs naturally only in groves on the western slopes of the Sierra Nevada Mountains of California. It is named after Sequoyah (1767–1843), the inventor of the Cherokee syllabary.
Giant Sequoia (Sequoiadendron giganteum) - Growth
Giant Sequoias thrive in full sun. They are not as tall as their relatives (Sequoia sempervirens). In their native environment they can reach 310' tall, but they have massive trunks. Trunks can reach close to 60' in diameter. Giant Sequoias are hardier than Coast Redwoods. They perform better in colder, higher elevations than they would along the coasts.
Giant Sequoia (Sequoiadendron giganteum) - Planting
It is important to recognize that these trees will get very large and you should have a garden that can accommodate their eventual size. In spring plant seeds in pots and protect the saplings from cold snaps. After 2 years of growth, they can be planted in the ground.
Giant Sequoia (Sequoiadendron giganteum) - Pest
Outside of their native climate, they are subject to being attacked from fungal diseases.
Giant Sequoia (Sequoiadendron giganteum) - Interesting facts
Giant Sequoias are the largest trees in the world by volume and are native to the Sierra Nevada mountains of California. The seeds of these trees require full sun and relatively fertile soil germinate and grow. In other words, the seeds and resulting seedlings need very little competition from other plants to survive. In nature, these trees overcome this obstacle by primarily releasing seeds from the female cones during wildfires. The dry heat resulting from a fire causes the cones to open and promotes seed dispersal. The wildfire has cleared away vegetation close to the ground and has provided fertility to the young germinating seeds. Additionally, the bark of the Giant Sequoias is rather fire resistant, so the parental trees will not die from a typical wildfire. Giant Sequoias require a large volume of water once they are established which is why they are generally found in nature close to streams.
Giant Sequoia (Sequoiadendron giganteum) - Soil and irrigation
They need regular water once established. Provide moderately fertile soil that drains very well.
